Giving null or wrong output,any problem in code?

ios_base::sync_with_stdio(false) cin.tie(nullptr) does this makes code accept user input in new line?

len=strlen(b); int t; for(x=0;x<len-1;x++) { for(;i<len-i;i--) { if(b[i+1]<b[i]) { t=b[i]; b[i]=b[i+1]; b[i+1]=t; } } } printf("%s",b); return 0;

You're finding out the length of an integer array using strlen?

what does ?(question mark) operator do in c++

Sure, no worries. I'm thinking about making a playlist on youtube about C++. Would anyone here watch it? 🤔

I ?

while i use the relative path in headfile.cpp to load an image can the file main.cpp including the headfile.h load the correct image?

Code looks ok, can you add a newline char in the print to avoid confusion for yourself and check again

Yes

What was the input you gave?

#Puzzle (Beginners) What will be the output of this program?

I thought so. Your program would exhibit Undefined Behavior. An int is capable of storing not more than 12! and an unsigned long long is capable of storing factorials till 20!. So your code would result in an overflow and overflow on signed integers is Undefined Behavior

What should use to get factorial <100

If this is some online contest, I doubt you would be required to calculate such big factorials. Most likely, it would involve an algorithm using which you can solve it without calculating such large factorials. If you must calculate them then use a library like GMP. They have a class called BigNum with infinite precision limited only by the virtual memory your OS uses

Can anyone help me?

If I run this program it will work, I type any numbers on "Enter Number" and it will work but i can't type any letters on "Enter Name"

Use templates functions

How

I wonder how templates will help here :)

Hey bro

How you want your program to react if you type letters?

How you want your program to react if you type letters?

int main () { int i,n; int * p; cout << "Enter Number : "; cin >> i; p= new (nothrow) int[i]; if (p == 0) cout << "Error: memory could not be allocated"; else { for (n=0; n<i; n++) { cout << "Enter Name: "; cin >> p[n]; } } return 0; }

Can i pm u?

No pls

int main () { int i,n; int * p; cout << "Enter Number : "; cin >> i; p= new (nothrow) int[i]; if (p == 0) cout << "Error: memory could not be allocated"; else { for (n=0; n<i; n++) { cout << "Enter Name: "; cin >> p[n]; } } return 0; }

I'm here because im begging for help

I dont know how to program 😭

Create a code that will ask for a number then it Will ask names as many as the number Input

temp.cpp: In function 'int div(int, int)': temp.cpp:18:20: error: new declaration 'int div(int, int)' int div(int x,int y) ^ In file included from temp.cpp:2:0: c:\program files\dev-cpp\mingw64\x86_64-w64-mingw32\include\stdlib.h:358:17: error: ambiguates old declaration 'div_t div(int, int)' div_t __cdecl div(int _Numerator,int _Denominator); ^

Why you declared functions in main. You need declare them globally

#include <stdio.h> int main() int div(int x,int y); int mul(int x,int y); { int a,b... Like this?

#include <vector> #include <iostream> #include <string> using namespace std; int main() { size_t count; cout << "Enter Number: "; cin >> count; vector <string> names; for(int i = 0; i < count; i++) { string name; cout << "Enter name: "; cin >> name; names.push_back(name); } }

No. Like this: #include <stdio.h> int div(int x,int y); int mul(int x,int y); int main() { int a,b...

One more thing I am feeling i am very slow in logic making is there any way to improve

Hlo i have a ques.. A person has 100rs and 10rs is the cost price of 1 chocolate.and by returning 2 wrappers of chocolate he will get 1 extra chocolate.He took only odd no. Of chocolate and gave even no. Of chocolate to his friend and his friend will return him wrappers which he can further exchange with chocolates.He sell his friend a chocolate at5rs per choco. How to code this program in c++ plz help anyone.. 🥺🙏
