How to reset number to 0 after running program once again-CodePudding

I'm making program which converts sum of the numbers entered by user to binary, octal and hexadecimal. I would like to give a user an option to run program once again but with different numbers. Here is the problem - each time user repeats numbers, sum of these numbers are added to the previous entry. How do I stop incrementing? Is there any way to reset sum to 0? Thank you so much for your help!

Is there any way to reset sum to 0?

Yes, set sum to 0 right before the inner loop.

sum = 0;
while(1)
{
    printf("Enter number: ");
    scanf("%d", &value);
    sum  = value;
    if(value == 0)break;
}

Also, rather then using while (1) with a break condition at the end, use a do..while loop.

sum = 0;
do {
    printf("Enter number: ");
    scanf("%d", &value);
    sum  = value;
} while (value != 0);

You would simply need to reset your sum variable to 0 if the user wants to reuse the number system with other numbers -

printf("\nEnter numbers once again? (y/n)\n");
scanf(" %c", &j);
printf("\n\nENTERING ONCE AGAIN\n");

if(j == 'n'||j == 'N')break;
***else sum = 0***
