Prototype
int putch(int c);
Description
Outputs character to screen.
putch outputs the character c to the current text window. It is a text mode function performing direct video output to the console. putch does not translate linefeed characters (\n) into carriage-return/linefeed pairs.
The string is written either directly to screen memory or by way of a BIOS call, depending on the value of the global variable _directvideo.
Remarque : This function should not be used in Win32 GUI applications.
Return Value
On success, putch returns the character printed, c. On error, it returns EOF.
Example
#include <stdio.h>
#include <conio.h>
int main(void)
{
char ch = 0;
printf("Input a string:");
while ((ch != '\r'))
{
ch = getch();
putch(ch);
}
return 0;
}
