How to get the length of a string in C?

The most straightforward way to obtain the length of a string in C is by using the strlen function. This function is part of the C standard library (string.h) and is widely used for its simplicity and efficiency.

Here’s how you would do that:

#include<stdio.h>
#include<string.h>
int main(){
	char str[7] = "Hello";
	int len = strlen(str);
	printf("%u\n", len);
	return 0;
}

So this is how you would get the length of the string in C.

You can also get the length of a number in C, check out my article on this.
