Removing the last character from a string in C
To remove the last character from a string in C, you can use the strlen()
function to get the length of the string, then overwrite the last character with a null terminator \0
.
For example:
#include <string.h>
void remove_last_char(char str[]) {
int length = strlen(str);
str[length-1] = '\0';
}
int main() {
char str[] = "Hello";
remove_last_char(str);
printf("String after removing last char: %s\n", str);
return 0;
}
This gets the length of the input string str
using strlen()
, then overwrites the character at index length-1
with a null terminator. This effectively "removes" the last character by terminating the string one character earlier.
Printing the string after calling remove_last_char()
will output "Hell".
