what makes c++ different from other programming languages?

Can you help me out ? I wanna find repeated particular character in string and where it is repeated. By substr , i wrote the code but not getting it

Can you stop writing in bold text? It makes you look ridiculously self-important

Automatic

Seems like bullshit to me

Can i share?

Is there any one who can solve C++ loop statement question?

Is some exam going on and people are trying to cheat on it?

Hello I'm trying to read only lines from file which contains string, not the line whose starting character is '@' or blank lines... https://ideone.com/GWCneg here is the code, this code is able to avoid the lines starting with '@' but it is reading the blank lines...

Need help to understand line 24 please Does numPtr still hold the address of the last element when line 25 begins? https://pastebin.com/zaD4jZza

Try simple program like print anu

It is actually one past the last element when the first for loop ends. That is why the second loop begins with a numPtr--

hello, how to put a letter in a word in an array? C

You have array of chars and need to add char in array or what do you mean?

Hi to all. I'm not comfortable asking. But I hope for your help. I'm just starting to study C and faced a problem. I need that at the correctly entered data she passed me. I enter x = 3, y = 0. If I should skip because this is the correct data but it does not let further code. Maybe someone knows what the problem is. Thank you in advance

#include <stdio.h> #include <math.h> int main() { float x1, x2, x3, y1, y2, y3; float P, s, ab,bc,b,a,c,ac,p,S; printf("Введіть х1\n"); scanf("%f", &x1); printf("Введіть у1\n"); scanf("%f", &y1); if (((-3)<=y1<=0) && (y1<=(x1/2)) && (((x1*x1)+(y1*y1))<=9)){ printf("+"); }else{ return 0; } printf("Введіть x2\n"); scanf("%f", &x2); printf("Введіть у2\n"); scanf("%f", &y2); if ((-3<=y2<=0) && (y2<=x2/2) && ((x2*x2)+(y2*y2)<=9)){ }else{ return 0; } printf("Введіть x3\n"); scanf("%f", &x3); printf("Введіть у3\n"); scanf("%f", &y3); if ((-3<=y3<=0) && (y3<=x3/2) && ((x3*x3)+(y3*y3)<=9)){ }else{ return 0; } if ((x2-x1)*(y3-y2)==(x3-x2)*(y2-y1)==(x3-x1)*(y2-y1)==(x2-x1)*(y3-y1)){ printf("Лежать на одній прямій"); return 0; } ab=((x2-x1)*(x2-x1))+((y2-y1)*(y2-y1)); a=sqrt(ab); bc=((x3-x2)*(x3-x2))+((y3-y2)*(y3-y2)); b=sqrt(bc); ac=((x3-x1)*(x3-x1))+((y3-y1)*(y3-y1)); c=sqrt(ac); P=a+b+c; p=P/2; S=p*(p-a)*(p-b)*(p-c); s=sqrt(S); printf("Периметр трикутника-%.2f, Площа трикутника- %.2f",P,s); return 0; }

Yibuchiy sluchay for that naming

I do not choose the names but the task, but still why the first check for data x = 3, y = 0 does not work?

#include <stdio.h> #include <math.h> int main() { float x1, x2, x3, y1, y2, y3; float P, s, ab,bc,b,a,c,ac,p,S; printf("Введіть х1\n"); scanf("%f", &x1); printf("Введіть у1\n"); scanf("%f", &y1); if (((-3)<=y1<=0) && (y1<=(x1/2)) && (((x1*x1)+(y1*y1))<=9)){ printf("+"); }else{ return 0; } printf("Введіть x2\n"); scanf("%f", &x2); printf("Введіть у2\n"); scanf("%f", &y2); if ((-3<=y2<=0) && (y2<=x2/2) && ((x2*x2)+(y2*y2)<=9)){ }else{ return 0; } printf("Введіть x3\n"); scanf("%f", &x3); printf("Введіть у3\n"); scanf("%f", &y3); if ((-3<=y3<=0) && (y3<=x3/2) && ((x3*x3)+(y3*y3)<=9)){ }else{ return 0; } if ((x2-x1)*(y3-y2)==(x3-x2)*(y2-y1)==(x3-x1)*(y2-y1)==(x2-x1)*(y3-y1)){ printf("Лежать на одній прямій"); return 0; } ab=((x2-x1)*(x2-x1))+((y2-y1)*(y2-y1)); a=sqrt(ab); bc=((x3-x2)*(x3-x2))+((y3-y2)*(y3-y2)); b=sqrt(bc); ac=((x3-x1)*(x3-x1))+((y3-y1)*(y3-y1)); c=sqrt(ac); P=a+b+c; p=P/2; S=p*(p-a)*(p-b)*(p-c); s=sqrt(S); printf("Периметр трикутника-%.2f, Площа трикутника- %.2f",P,s); return 0; }

Im not sure that construction is allowed ((-3)<=y1<=0)

Interesting why? I think its work like (-3 <= y1) <= 0 then -3 <= 0 is true, true <= 0 is false

Hi guys, I'm struggling with a problem in C++, maybe you can help me where is the mistake 😊 below are the informations.Write a function called sumEvenDigit that receives a number and returns the sum of the even digits from that number. The function must be called sumEvenDigit. The function must receive an int parameter and return an int that stores the sum of the even digits of the given number. Limit: This number will be greater than 0 and less than 2 000 000 001. Example: sumEvenDigit(342) will return 6 #include <iostream> #include <iostream> using namespace std; int sumDigit(int sumEvenDigit{ int s=0; while(sumEvenDigit > 0) { if((sumEvenDigit % 10) % 2 == 0) s= s + sumEvenDigit % 10; sumEvenDigit= sumEvenDigit / 10; } return s; } int main() { int n; cin>>n; cout<<sumDigit(n); return 0; }

hello guys - i have question - i want start learning C programming can you offer to me best book ?

it is not the best

But it is good for a beginner

ok tnx also some people offer to me c-how-to-program-eighth-edition-deitel is it good ?

No idea

ok - tnx for share book name 👍🏻

hi guys,can someone help me how to fix it

Fix what?

Is there any C++ PDF guide that explains how each code function like for example what is #include <iostream> ,what it does etc ?

There's this website called learncpp dot com. It's very user-friendly.
