[Solved] Multi-functional math calculator in C

by


Your mistake is that you didn’t put a pause at the end of the main().

To fix it you can either put at the end of main command system(“pause”); or you could do it this way

 char c; std::cin >> c;
 return;

This way it will wait for character input and then if you want to terminate your application when you input ‘=’
you can write :

 if (c=='=') return;

Simple 🙂

If you want your calculator to do multiple calculations until you insert that ‘=’ sign. You can do it this way :

 int main()
{

char c;



while(c!='N'){

//YOUR CODE GOES HERE AND IT WILL BE REPEATED UNTIL YOU INSERT N at the end



std::cout << "\n Do one more calculation ? (Y/N) : ";
std::cin >> c;
}

system("pause");
return 0;
}

C:

    while(c!='N'){

    //YOUR CODE GOES HERE AND IT WILL BE REPEATED UNTIL YOU INSERT N at the end



//Doing it this way, if you type N it will terminate, if you type any other character it will do the loop.
printf(" Do one more calculation ? (Y/N) : ");
scanf("%c", &c);
}
