1) Write comments next to each line in order to explain what the code is doing?

#include

char (uy) (char a);

int main()

{

char p;

p = '1';

printf("Value of p is %c ", uy(p));

return 0;

}

char (uy) (char mmm)

{

char x;

x = mmm + mmm;

return x;

}

2) Rewrite the code given in Question 1 when the function prototype changes to char (uy) (char*);
