在 C++ 中,每个字符都有一个内部 ASCII 值。在此 C++ 程序中,我们查找给定字符串中 ASCII 值之和。在此 C++ 代码中,我们使用 for 循环 (for(int i = 0; i < txt.size(); i++)) 来迭代从 0 到字符串长度的值。在其中,我们将字符串中每个字符的 ASCII 值添加到 txtASCII_Sum (txtASCII_Sum = txtASCII_Sum + txt[I];) 中。此处,cout << “\nThe ASCII Value of “<< txt[i] << ” = ” << (int)txt[i]; 语句会打印每个字符串字符的 ASCII 值。
#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++ 程序使用 While 循环查找字符串中 ASCII 值之和
#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;
}

The Sum of ASCII Value in tutorial gateway String = 1670
使用 For 循环和函数查找字符串中 ASCII 值之和的 C++ 程序。
#include<iostream>
#include<string.h>
using namespace std;
int sumOfASCIIValuesinaString(string txt)
{
int txtASCII_Sum = 0;
for(int i = 0; i < txt.size(); i++)
{
cout << "\nThe ASCII Value of "<< txt[i] << " = " << (int)txt[i];
txtASCII_Sum = txtASCII_Sum + txt[i];
}
return txtASCII_Sum;
}
int main()
{
int Sum = 0;
string txt;
cout << "Please Enter any String you want = ";
getline(cin, txt);
Sum = sumOfASCIIValuesinaString(txt);
cout << "\n\nThe Sum of ASCII Value in "<< txt << " String = " << Sum;
return 0;
}
Please Enter any String you want = hello
The ASCII Value of h = 104
The ASCII Value of e = 101
The ASCII Value of l = 108
The ASCII Value of l = 108
The ASCII Value of o = 111
The Sum of ASCII Value in hello String = 532
