Yes, I mean some 3rd party libraries

Who's here dot net developer

I am trying to write a program that divides an input into the smallest denomination of bills (50, 20, 10, 5, 1), and I have it mostly working great but for some reason it stops after displaying the amount of 5's. #include <stdio.h> int main() { int input = 0, amount = 0, remainder = 0; int bills[] = {50, 20, 10, 5, 1}; printf("Enter an amount of dollars\n"); scanf("%d", &input); for(int i = 0; i < input; i++) { amount = input / bills[i]; remainder = input - (amount * bills[i]); if (remainder > 0) { input = remainder; } printf("That is.. %d $%d\n", amount, bills[i]); printf("%d\n", remainder); } return 0; } Output: Enter an amount of dollars 98 That is.. 1 $50 That is.. 2 $20 That is.. 0 $10 That is.. 1 $5 uncommenting the last printf statement shows that the remainder is 3 in the above example. I have tried changing the for statement to > 4, and adding an else. I am lost. i've also tried changing the input to tons of different values, but it always stops before the last loop. can anyone explain to me why it just stops at the 5's?

print i and input at the end of the loop ...

how to do this one？ thankyou

You are to use Visual Studio to write a simple desktop calculator that uses postfix notation. Postfix provides two operands and finally an operator. The following shows the typical input and output of a calculator like this: 30 5 + 35 This means that the program takes the numbers 30 and 5 and uses the operator + to add them and then prints the result. You should write a program which will: • Read 2 floating point numbers, • Read an operator (+, -, *, /, %) • Check for error conditions such as a missing or unknown operator, division by zero, modulus by zero or trying to do modulus on non-integral values • Print either an error message or the result of the calculation and then terminate • If the result of the calculation is an integer, it should be printed with no places after the decimal. You should submit: • A program calculator.c that runs on Visual Studio, • A file reflect.txt that answers the reflections below • Since Blackboard only allows one file to be attached, you can combine these into a single zip file for submission. Or , you can write your reflections (preffered) in the .c file at the bottom after your code. Reflections 1. Describe the decision structure you used to perform the calculation for the different operators. Why did you pick this decision structure over the competing ones? 2. How did you determine if the numbers you read were integers or floating point? Describe your technique in detail.

ok then usual way of asking online is to show your code and error .. if too long then use one of the online pasting services ... so someone who knows can help you

Is dot net C++ library?

If i have an array and i want to fill this array by default value = 5 I made it like that.. ____________ array < int , 6 > arr ; arr.fill(5); —————————— Can i made it by another way !?

What is efficiency of online free compilers and Free IDEs to compile STL Code? I am using vector and linked list in VS code and eclipse ide and its always showing some warnings

What's wrong? while( (i < 10) && (i > 24)) A. the logical operator && cannot be used in a test condition B. the while loop is an exit-condition loop C. the test condition is always true D. the test condition is always false

D

Why?

Why?

U know a number that less than 10 and more than 24?

cauz When if i is less than 10 then it can never be greater than 24 and, The operator && means both condition should be true then only while loop will run.

Thanks

It will be compiler error right?

Is it c , and why?

Can any number be greater than 24 and less than 10 ?

Another question, what happened if we modify a const array?

Is it logical or run time or compiler error?

Ideally for this example the suffix should advance to the next occurrence of the first character in the string. This is also however not suitable for large strings that I mentioned in my previous post. So if the string provided is sandsansand then the suffix should start with s at position 4 and then advance to s at position 7. That is it. The algorithm provided in GFG does the same but it does this through a circuitous route in the else part of your program.

// Efficient CPP program to find length of // the longest prefix which is also suffix #include<bits/stdc++.h> using namespace std; // Returns length of the longest prefix // which is also suffix and the two do // not overlap. This function mainly is // copy computeLPSArray() of in below post // https://www.geeksforgeeks.org/searching-for-patterns-set-2-kmp-algorithm/ int longestPrefixSuffix(string s) { int n = s.length(); int lps[n]; lps[0] = 0; // lps[0] is always 0 // length of the previous // longest prefix suffix int len = 0; // the loop calculates lps[i] // for i = 1 to n-1 int i = 1; while (i < n) { if (s[i] == s[len]) { len++; lps[i] = len; i++; } else // (pat[i] != pat[len]) { // This is tricky. Consider // the example. AAACAAAA // and i = 7. The idea is // similar to search step. if (len != 0) { len = lps[len-1];👈👈👈👈 // Also, note that we do // not increment i here } else // if (len == 0) { lps[i] = 0; i++; } } } int res = lps[n-1]; // Since we are looking for // non overlapping parts. return (res > n/2)? res/2 : res; } // Driver program to test above function int main() { string s = "abcab"; cout << longestPrefixSuffix(s); return 0;

Same step in the efficient approach also ..it's tricky ...didn't find proper explanation anywhere

No this is different. Here it doesnt just blindly go to the next suffix string search. Here the string is preprocessed earlier to determine where the next search should be made. And like I said earlier, such algorithms make a difference only when the input string is really large like a genome sequence.

Okay ..what is Len = LPS[len-1] doing

Hi guys i have taken an exam by hacker earth in C++. Even though i know fundemental programming i could not clear one single programming question due to time constraint! Is it possible fr people other than IT and Computer science to crack this exam?

It is possible but it requires not only the fundamentals of programming, also a huge practice of problem solving, Me also, only by knowing the basic programming in C, gone through hackerrank coding exam and failed, but now after a year, those problems are so tiny for me due to practice :)

Can you help me about c++? Please immediately

I need a help here a c++ problem Qn "Write a function which output all the prime numbers between 2 and a given positive integer 'n'."

is Range of N given?

i give you a hint ... google it

Nop the question is it is

#include<iostream> using namespace std; bool isPrime(int n) { if(n==1) return false; for(int i=2; i*i <= n; i++) if(n%i==0) return false; return true; } bool printPrime(int n) { for(int i=2; i<=n; i++) { if(isPrime(i)) cout<<i<<" "; } } int main() { int n; cin>>n; printPrime(n); return 0; }

Ehh let people make efforts.

What is the warning shown?

#include <iostream> #include <string> #include <vector> using namespace std;   int main() {          vector<string> myvector{ "This", "is",                              "Geeksforgeeks" };       // using begin() to print vector     for (  it = myvector.begin();          it != myvector.end(); ++it)         cout << ' ' << *it;     return 0; }

#include <iostream> #include <string> #include <vector> using namespace std;   int main() {          vector<string> myvector{ "This", "is",                              "Geeksforgeeks" };       // using begin() to print vector     for (  it = myvector.begin();          it != myvector.end(); ++it)         cout << ' ' << *it;     return 0; }

it object not declared in this scope

You havent specified the type of it. Use this : for (auto it = myvector.begin(), it != ...)

I'm sorry but i think that ( it ) is Undeclaration.

Can function of type string return a value??? Like this ??? Thank you... string getText() { string text; cout <<"Enter Text....."; getline (cin,text); return text; }
