In this section, we will write a C program to find the length of a string using strlen() function. But before, you may go through the following topic in C programming.
The program will take the user input for the string. To find the length of a string, we use the built-in string function called strlen(). This function is present in the string.h header file.
C Program to Find Length of a String Using strlen() Function
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | // C program to find length of the string using strlen() function #include <stdio.h> int main() { char str[30]; int length; printf("Enter a string: "); scanf("%s", str); length = strlen(str); printf("Length of %s is %d", str, length); return 0; } |
Output:
Enter a string: simple2code
Length of simple2code is 11
