In this article, we will discuss the concept of C++ program to count the total words in the given string
In this post, we are going to learn how to count the total number of words in the given string in C++ programming language
The program allows the user to enter a string thereafter It counts the total words of the given string using for loop in C++ language
Program 1
#include <iostream> #include <stdio.h> #include <conio.h> using namespace std; int main() { char str[100]; int i,count=1; cout << "Enter a String:" << endl; gets(str); for(i=0; str[i]!='\0'; ++i){ if(str[i]==' ') count++; } cout << "The total number of words in the given String: "<<count; getch(); return 0; }
When the above code is executed, it produces the following result
Enter a String: C++ is an OOP language The total number of words in the given String: 5
Approach
The program allows the user to enter a string thereafter It counts the total words of the given string using while loop in C++ language
Program 2
#include <iostream> #include <stdio.h> #include <conio.h> using namespace std; int main() { char str[100]; int i,count=1; cout << "Enter a String:" << endl; gets(str); i=0; while(str[i]!='\0'){ if(str[i]==' ') count++; ++i; } cout << "The total number of words in the given String: "<<count; getch(); return 0; }
When the above code is executed, it produces the following result
Enter a String: C++ language supports to the procedural way The total number of words in the given String: 5
Approach
The program allows the user to enter a string thereafter It counts the total words of the given string using do-while loop in C++ language
Program 3
#include <iostream> #include <stdio.h> #include <conio.h> using namespace std; int main() { char str[100]; int i,count=1; cout << "Enter a String:" << endl; gets(str); i=0; do{ if(str[i]==' ') count++; ++i; }while(str[i]!='\0'); cout << "The total number of words in the given String: "<<count; getch(); return 0; }
When the above code is executed, it produces the following result
Enter a String: C++ is a general-purpose programming language The total number of words in the given String: 7
Approach
