Write a program to find string length in c

Program to Find String Length in C

In C programming, a string is a sequence of characters that is terminated by a null character \0. The length of a string is the number of characters in the string, excluding the null character.

The length of a string is an essential concept in C programming because it is used in many standard library functions that operate on strings. For example, the strlen function is a standard library function in C that returns the length of a string. The strcpy function copies a string from one location to another, and the strcat function concatenates two strings.

Example of a string finding String length in C:

This program uses a while loop to count the number of characters in the string str. The loop keeps iterating until it reaches the null character \0, which marks the end of the string. The length variable is incremented each time the loop iterates, so it contains the length of the string when the loop is finished.

C programming

#include
int main()
{
    char s[10];
    int i;
    printf("Enter the string:");
    scanf("%s",s);
    printf("string is: %d\n",s);
    for(i=0;s[i];i++);
    printf("String length is:%d\n",i);
}

Output:

Enter the string: ELECTRO4U
string is: ELECTRO4U
String length is:9
