C++ Program to Find the Sum of ASCII Value of All Characters in the String

This is a C++ Program to Find the Sum of ASCII Value of all Elements in a String.

Problem Description

The program takes a string and prints the sum ASCII values of all the characters.

Problem Solution

1. The program takes a string.
2. Using a for loop, the ASCII equivalent of each character is added.
3. The resultant sum is printed.
4. Exit.

C++ Program/Source code

Here is the source code of C++ Program to Find the Sum of ASCII Value of all Elements in a String. The program output is shown below.

```
#include<iostream>
```
```
using namespace std;
```
```
int main ()
```
```
{
```
```
    char str[50];
```
```
    int i, sum = 0; 
```
```
    cout << "Enter a string : ";
```
```
    gets(str);
```
```
    for (i = 0; str[i] != '\0'; i++)
```
```
        sum = sum + str[i];
```

    cout << "Sum of all characters : " << sum;

```
    return 0;
```
```
}
```

Program Explanation

1. The user is asked to enter a string. It is stored in ‘str’.
2. A variable ‘sum’ is initialized as 0.
3. Using a for loop, ASCII value of every character in the string is added to sum.
4. The total sum of the characters is then printed.
