Single quotes vs. double quotes in C or C++?

Question

When should I use single quotes and double quotes in C or C++ programming?

Answer 1

// In C and C++, single quotes are used for characters...

// and double quotes are used for strings

// Note: in Python and JavaScript, both single and double quotes

// are used for strings

#include <iostream>

#include <string>

int main(int argc, const char* argv[]) {

char c = 'A';

printf("c is: %c\n\n", c);

// and double quotes are used for strings

// C++ version

std::string std_string = "this is a standard string in C++...";

// C version

char c_string[] = "C type string, with a \'\\0\' at the end...\n";

std::cout << "print out both strings in C++...\n";

std::cout << "std_string is: \n\t" << std_string

<< " \n... and c_string is: \n\t" << c_string << "\n";

// You can get the c_string part of a std::string using c_str()

const char* pstd_string = std_string.c_str();

printf("Printing std_string through its c_str() method...\n\t%s\n\n",

pstd_string);

return 0;
