This question is actually very simple. It can be said that it does not require much brainstorming. I believe that many people will not see this. It is the same sentence I said before. Any simple thing has its meaning.
Perhaps this question can help you familiarize yourself with the method of string length.

#include<stdio.h>
#include<String.h>
int main(){
    
    
	char strs[100];
	scanf("%s",strs);
	printf("%d",strlen(strs)); 
	return 0;
}
