convert string to ASCII value

I was new to C++. I trying to convert a string(example : hello) into ASCII value. I tried to use putchar(0, but it only work for one character.

if I want to declare the char string become char string[80], then what are the following steps should I take??? Thank you for your time.

# include <iostream.h>
# include <string.h>
# include <stdio.h>

void main(){

char string;

cout<<"Enter a string : ";
cin>>string;

cout<<"The string you entered is "<<string<<endl;
cout<<"The ASCII value for that string is "<<putchar(string);

}

Code:

---

char string[80];

cout<<"Enter a string : ";
cin.getline(string,80,'\n');

---

# include <iostream.h>

void main(){

char string[80];

cout<<"Enter a string : ";
cin.getline(string,80,'\n');


cout<<"The string you entered is "<<string<<endl;
cout<<"The ASCII value for that string is "<<string;

}

if what I want to display is the ASCII value of H+e+l+l+o = ??, which line in the coding should I change? thank you.

You want the sum of the ASCII values? Use a for loop:

Code:

---

#include <string.h>

int ReturnASCIISum(char* String)
{
  int TotalSum = 0;
  for(int i=0; i<strlen(String); i++)
  {
      TotalSum += (int)String[i];
  }
  return TotalSum;
}
