Lengths of strings
#include <stdio.h>
int main(void)
{
char str1[] = "AAA";
int count = 0;
while (str1[count] != "\0") /* Increment count till we reach the string terminating character.*/
count++;
printf("\nThe length of the string \"%s\" is %d characters.", str1, count);
return 0;
}
The length of the string "AAA" is 3 characters.
