#include<stdio.h> int main() { static int a[20]; int i = 0; a[i] = i ; printf("%d, %d, %d\n", a[0], a[1], i); return 0; }
Step 2: int i = 0; here vaiable i is declared as an integer type and initialized to '0'(zero).
Step 3: a[i] = i ; becomes a[0] = 0;
Step 4: printf("%d, %d, %d\n", a[0], a[1], i);
Here a[0] = 0, a[1] = 0(because all staic variables are initialized to '0') and i = 0.
Step 4: Hence the output is "0, 0, 0".
#include<stdio.h> int X=40; int main() { int X=20; printf("%d\n", X); return 0; }
/* myprog.c */ #include<stdio.h> #include<stdlib.h> int main(int argc, char **argv) { int i; for(i=1; i<=3; i++) printf("%u\n", &argv[i]); return 0; }If the first value printed by the above program is 65517, what will be the rest of output?
#include<stdio.h> #include<stdlib.h> int main() { int *p; p = (int *)malloc(20); /* Assume p has address of 1314 */ free(p); printf("%u", p); return 0; }
