Is there any way to change the value of constant variables during program execution in C?

Question

I LOVE C PROGRAMMING 😘

Answer 1

Yes, but it is not enough to use a pointer as it has an undefined behaviour (meaning that different compilers may give you different results). You have to instead cast the pointer to int* and dereference it again. I'll explain better with code:

const int c = 10;
*(int *)&c = 0;
printf("c is %d", c); //c is 0
