How to count the number of spaces in a string in C++

By Raj Gaurav

hello everyone, in the previous tutorial we learned how to count the number of lines in a text file in C++, in this tutorial we will learn about how to count the number of spaces in a string in C++. Let’s see an example, suppose I’m entering a string like Hello everyone, I’m Raj Gaurav.

In the given string the spaces are 4.
but how can we find this with the help of c++ code?
let’s see the source code:

Source code: how to count the number of spaces in a string in C++

#include<iostream>
#include<string>
using namespace std;

int main()
{
        string s;
        int a,i,count=0;
 
        cout<<"Enter The String: ";
        getline(cin,s);
 
        a=s.size();
 
        for(i=0;i<a;i++)
       {
                if(s[i]==' ')
                {
                  count++;
                }
       }
 
        cout<<" The Number Of Spaces In The String: "<<count;
 
        return 0;
}

in this above piece of code we use getline() function.  getline() function is a c++ liabrary function, used to read a line.
we also use count() that returns the number of occurrence of an element in a given range.
general synatx of getline():  getline(char *string, int length, char deliminator).
getline() is present in the <string> header, The return type of getline() function is also of type istream.
in this code we also use For() loop. if you don’t know how to use for loop read here: how to terminate a loop

output:    Enter The String: My name is Raj Gaurav.
                  The Number Of Spaces In The String: 4.
