String length

Write a program to find the length of the string entered as command-line input.

#include<stdio.h>
#include<stdlib.h>
int main(int argc,char**argv)
{
	int i;
	if(argc < 2)
	{
		printf("Enter at least one argument\n");
		return 0;
	}
	for(i = 0;argv[1][i];i++);
		printf("Length = %d\n",i);
	return 0;
}

./a.out LotToLearn
