This is the code:
#include <iostream>
#include <string>
#include <cstdlib>
#include <sstream>
int main()
{
char str1[100];
char str2[100];
getline(str1,100,'\n');
getline(str2,100,'\n');
return 0;
}
I want to read string and store it in array so I in am using this method but it shows the following error on compiling
[Error]138: error: `getline' was not declared in this scope
What is the method of reading string in array.?
getline is a member of cin (which belongs to the std namespace). You need to say:
std::cin.getline(...)
Test.
Though I would personally recommend this:
#include <string>
#include <iostream>
int main()
{
std::string str1;
std::string str2;
std::getline(std::cin, str1);
std::getline(std::cin, str2);
return 0;
}
char str1[100] array. So maybe you should tell him to strcpy or persuade him against C-Style strings.
cin.getline instead, which works with char*'s. Edited.
std::cin.getline(...). See this for a runnable example.Please use gets() or (for Microsoft compiler gets_s() (with buffer length check ))
#include <iostream>
#include <string>
int main()
{
char str1[100];
char str2[100];
gets(str1);
gets(str2);
return 0;
}
gets, use fgets or gets_s, and gets_s is standard C now (since C11)
gets is wrong in every circumstance.
gets is always wrong. This is because it just writes in memory until in happens to meet the newline character in standard input. You can't restrict it, so your app will always suffer from buffer overflow. Buffer overflow accounts for 40% of security bugs in the software.gets was so bad it was removed altogether from C, where it originated from. There wasn't, there isn't and there won't be any reason to use gets, as at the same time as gets existed, fgets was the safe solution for reading single line to memory in C. And in C++ you can banish all these memory bugs out of existence just by using the correct function and correct idioms.
