Where did i go wrong

for some reason when it finishes one time and person enters 1(to check again) it doesn't ask for a string(or number) it just finishes on its own!!(run the code in some other compiler if it doesn't run here) https://code.sololearn.com/cdxTkFa1EDQN/?ref=app

hi, use scanf("%s",a); // instead of gets(a); this is making a infinite loop inside the code/program. rest everything is fine.

hi, hello sayeef, i have refreshed the code: this is working. pleas try this. --------------------------------------- //A number is called a spy number, if the sum and product of its digits are equal. #include<stdio.h> #include<string.h> #include<conio.h> int main() { c: char a[20]; int d,b,mul=1,add=0; printf("Please enter a number to check if it's a spy number or not:\n\nNumber:"); scanf("%s",a); printf("\nmultiplication:"); for(d=0; d!=strlen(a); d++) { mul=mul*(a[d]-'0'); } printf("%d\n\n", mul); printf("addition:"); for(d=0; d!=strlen(a); d++) { add=add+(a[d]-'0'); } printf("%d\n\n", add); if(add==mul) { printf("Because the sum and the product of the digits are equal, the number is a spy number."); } else printf("Because the sum and the product of the digits are not equal, the number is not a spy number."); printf("\n\nenter 1 to check again and enter 2 to exit"); scanf("%d", &b); switch(b){ case 1: goto c; case 2: break; } }

hi, @sayeef till i know; ------------- 1) there is some clash in the class of the main and stdio.h with the string operations performed in the class. ///// Or ///// 2) errors between a c functions used and c++ functions used at the same time in a program ///// Or///// 3) functions not defined correctly. So, try to define a separate function , in the main class for multiplication and addition. do not make loops like while , for ( more than 1 loops ) inside the main class //( this could produce an infinite loop) // and the program would not terminate correctly. // #C++ #Programming #Codding

Sayeef i already do it.. there is no problem but you did a little mistake.. you define literal at the top in c we define variable from the start..
