我可以轻松创建字符串和cout的名字，但有麻烦
找到如何打印每个字符串的第一个字母

std :: string，你应该用来表示每个名字，有一个
你可以用来提取第一个字符的成员函数的数量。
例如''at''成员函数。
- -
答：因为它弄乱了人们通常阅读文字的顺序。
问：为什么这么糟糕？
A：热门发布。
问：usenet和电子邮件中最烦人的是什么？
谢谢...
请理解这是一个简介的开头。
编程类
这个成员函数从未提及过...... 。
我包括字符串...
我现在所需要的一切s找出如何打印第一个字符
也许使用忽略功能？
#include< iostream>
#include< string>
使用命名空间std;
int main（）
{
字符串优先;
字符串中间;
字符串最后;
cout<< 以First Middle Last：格式输入名称：
cin>>首先;
cin>>中间;
cin>>最后一个;
cout<<第一个<< endl<<中<< endl<<最后<< endl;
返回0;
}

请理解这是编程类介绍的开始。
这个成员函数从未提及过......
我包括字符串...
现在我需要的是找出如何只打印第一个字符
也许使用忽略功能？
#include< iostream>
#include< string>
使用命名空间std;
int main（）
{
字符串优先;
字符串中间;
字符串最后;
cout<< 以First Middle Last：格式输入名称：" ;;
cin>>首先;
cin>>中间;
cin>>最后;
cout<<第一个<< endl<<中<< endl<<最后<< endl;
返回0;
}
哦，如果它们是3个单独的字符串那就是'更简单。
first [0]首先是std :: string的第一个字符。
middle [0]是第一个字符std :: string middle等..
所以
std :: cout<<首先[0]<<中[0]<<最后[0]<< std :: endl;
将打印他们的姓名首字母。
它是[0]而不是[1]，因为在C和C ++中，数组元素从0开始，
不是1.
I have a question in my class.. hoping to get some help
I need to create a program that will print
firstName middleName lastName
then their initials
User will input:
John Smith Doe
Output:
John
Smith
Doe
JSM
I can easily create the strings and cout the names but having trouble
finding how to print the first letter of each string
(cannot use array)
am I to use ignore function somehow?
can anyone help me????

std::string, which you should be using to represent each name, has a
number of member functions you can use to extract the first character.
The ''at'' member function, for example.
--
A: Because it messes up the order in which people normally read text.
Q: Why is it such a bad thing?
A: Top-posting.
Q: What is the most annoying thing on usenet and in e-mail?
thank you...
Please understand this is the very beginning of a intro to comp
programming class
this at member function is never mention as of yet...
I am including string...
All I need now is to find out how to just print the first character
maybe the use of the ignore function?
#include <iostream>
#include <string>
using namespace std;
int main()
{
string first;
string middle;
string last;
cout << "Enter a name in the format First Middle Last: ";
cin >> first;
cin >> middle;
cin >> last;
cout << first << endl << middle << endl << last << endl;
return 0;
}

return 0;
}
Oh, if they are 3 seperate strings it''s even much easier.
first[0] is the first character of the std::string first.
middle[0] is the first character of the std::string middle, etc..
so
std::cout << first[0] << middle[0] << last[0] << std::endl;
would print their initials.
It is [0] instead of [1] because in C, and C++, array elements start at 0,
not 1.
