A program to find length of string

Here is my code:

#include<stdio.h>
#include<string.h>
int string_length(char s[]);
main()
{
        char s[50];
        int l;
        printf("Enter the string\n");
        scanf("%s\n",s);
        l=strlen(s);
        printf("Length of string = %d\n",l);
}
int string_length(char s[])
{
        int i;
  开发者_开发技巧      i=0;
        while(s[i] != '\0')
                ++i;
                return i;

}

After compile it scan for two input values.

What's wrong with my code?

Get rid of the newline in the scanf.

scanf("%s",s);

That should get this code to work.

But I am unable to understand why you wrote a function to compute string length if you had to use strlen().

HTH,
Sriram.

You're calling strlen instead of your own string_length in main.

const size_t sillyStrlen(const char* text) {
  if (*text) {
    return sillyStrlen(text + 1) + 1;
  }
  return 0;
}

1. Buy a book, see The Definitive C Book Guide and List
2. Read about the language syntax
3. Learn how to use pointers
4. You've just learned how to write a int strlen(char[]) function.

Try This one.

#include<stdio.h>
#include<conio.h>
#include<string.h>
int main()
   {
    char *str;
    printf("Enter a string\n");
    gets(str);
    printf("The size of the string is %d",strlen(str));
    getch();
    return 0;
    }
