C Program Find String Length
/* C program to calculate and print length of given string without using built-in function. */ #include<stdio.h> #include<string.h> int main() { int i,length; char str[100]; printf("Enter a String to find its length:"); gets(str); i=0; while(str[i]!='\0') i++; printf("Using own code, The length of string '%s' is = %d",str,i); printf("\nUsing Predefined Function strlen() The length is = %d",strlen(str)); return 0; }
Output
Enter a String to find its length:ABCDE
Using own code, The length of string ‘ABCDE’ is = 5
Using Predefined Function strlen() The length is = 5
