#include <stdio.h>

void main() {
    char a[15] = "!Hello world!";
    a[0] = '';
    printf_s("%s",a);
    getch();
}

I want to remove only one ! which is in the beginning but using a[0]=''; gives error and a[0]=0; works as '\0'. The output I want is Hello world!. How can I achieve this?

Looks like a duplicate of [c remove the first character of an array](https://stackoverflow.com/questions/5711490/c-remove-the-first-character-of-an-array). TL;DR: you can't do it directly, but there are workarounds using pointers. – blackbrandt Sep 22 '22 at 11:56
try `printf("%s", a + 1);` – tstanisl Sep 22 '22 at 12:00
@tstanisl But I want to save that result to a variable. – Himanshu Sep 22 '22 at 12:03
so try `char *b = a + 1;` – tstanisl Sep 22 '22 at 12:12
Try [`memmove()`](https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/memmove-wmemmove?view=msvc-170). – Weather Vane Sep 22 '22 at 12:43
