Describe the effect of the following function in English and briefly describe how it works. (What is the role of each variable and instruction in the overall result?)

int f(char* x) { char* y = x; while(*y++); while(*(--y) != *x); return y-x; }

You may run this function to help figure it out. To pass it a string argument, youll need to statically create the strings, as in the following:

char str[3]; str[0] = h; str[1] = i; str[2] = 0;
