Hello,
I have written in C a program that calculate the sum of digits (for a number).
For Example for the number 199 the checksum is 19.
But now i want that my program also calculate the checksum of 19.
How can i do that in C? Can i make a nested function in C?
Here is my code
Code:int dsum(int z) { int q=0; while(z>0) { q+= z%10; z /=10; } return q; } int main(){ int z =199; int i; int qs= dsum(z); printf("%d", qs); return 0;}
