C++ Program to find Sum of ASCII values in a String

In C++, every character has an internal ASCII value. In this C++ program, we find the sum of ASCII Values in a given string. In this C++ code, we used for loop (for(int i = 0; i < txt.size(); i++)) to iterate values from 0 to string length. Within that, we are adding the ASCII value of each character in a string to txtASCII_Sum (txtASCII_Sum = txtASCII_Sum + txt[I];). Here, cout << “\nThe ASCII Value of “<< txt[i] << ” = ” << (int)txt[i]; statement prints the ASCII value of each string character.

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

int main()
{
	int txtASCII_Sum = 0;
	string txt;
	
	cout << "Please Enter any String you want  =  ";
	getline(cin, txt);
	
	for(int i = 0; i < txt.size(); i++)
	{
		cout << "\nThe ASCII Value of "<< txt[i] << " = " << (int)txt[i];
		txtASCII_Sum = txtASCII_Sum + txt[i];
	}
	
	cout << "\n\nThe Sum of ASCII Value in "<< txt << " String = " << txtASCII_Sum;
		
 	return 0;
}

C++ Program to find Sum of ASCII values in a String using a While loop

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

int main()
{
	int i = 0, txtASCII_Sum = 0;
	string txt;
	
	cout << "Please Enter any String you want  =  ";
	getline(cin, txt);
	
	while(i < txt.length())
	{
		cout << "\nThe ASCII Value of "<< txt[i] << " = " << (int)txt[i];
		txtASCII_Sum = txtASCII_Sum + txt[i];
		i++;
	}
	
	cout << "\n\nThe Sum of ASCII Value in "<< txt << " String = " << txtASCII_Sum;
		
 	return 0;
}
