Problem Statement
Display an extended (non ASCII) character onto the terminal. Specifically, display a £ (GBP currency sign).
Let's start with the solution:
Step by Step solution about How to resolve the algorithm Terminal control/Display an extended character step by step in the C programming language
The provided C code snippet contains two print statements:
-
puts("£")
: This statement prints the British pound sign "£" to the standard output. The pound sign is enclosed in double quotes as it is a character literal. -
puts("\302\243")
: This statement prints the Euro symbol "€" to the standard output. However, it uses an escape sequence to represent the Euro symbol. Here's a breakdown of the escape sequence:\302
: This represents the first byte of the UTF-8 encoding of the Euro symbol. In hexadecimal, it is 0x302.\243
: This represents the second byte of the UTF-8 encoding of the Euro symbol. In hexadecimal, it is 0x243.
When the puts
function encounters this escape sequence, it interprets it as a UTF-8 encoded character and prints the corresponding Euro symbol "€".
So, when you run this program, it will print the British pound sign "£" followed by the Euro symbol "€" on the standard output. The exact output may vary depending on the terminal or console you are using and its support for UTF-8 encoding.
Source code in the c programming language
#include <stdio.h>
int
main()
{
puts("£");
puts("\302\243"); /* if your terminal is utf-8 */
return 0;
}
