What is the C plus plus code to print all ASCII codes and the equivalent characters?

Answer 1

Although character data types such as char are intrinsically numeric, whenever you print a char you automatically print the symbol associated with the character code (the char's value), never the code. In order to print the code you must cast the character to a numeric data type, such as int.

char c = 'A'; // ASCII value 65 decimal (0x41)

std::cout << static_cast<int>(c); // puts the value 65 on std::cout

Answer 2

#include<iostream>

int main()

{

for(int i=0; i<256; ++i)

std::cout<<i<<" = "<<(char) i<<std::endl;

return(0);

}
