Last Updated : 06 Oct, 2023

The putchar(int ch) method in C is used to write a character, of unsigned char type, to stdout. This character is passed as the parameter to this method.

Syntax:

int putchar(int ch)

Parameters: This method accepts a mandatory parameter ch which is the character to be written to stdout.

Return Value: This function returns the character written on the stdout as an unsigned char. It also returns EOF when some error occurs.

The below examples illustrate the use of putchar() method:

Example 1:

C

// C program to demonstrate putchar() method

#include <stdio.h>;

int main()
{

    // Get the character to be written
    char ch = 'G';

    // Write the Character to stdout
    putchar(ch);

    return (0);
}

Output

Example 2:

C

// C program to demonstrate putchar() method

#include <stdio.h>;

int main()
{

    // Get the character to be written
    char ch = '1';

    // Write the Character to stdout
    for (ch = '1'; ch <= '9'; ch++)
        putchar(ch);

    return (0);
}
