What is the difference between putchar and printf

Difference: The putchar() function can only output a single character, while the printf() function can output various types of data, such as character, floating point, and integer types; "printf("%c", 'A')" is equivalent to "putchar('A')". If you only want to output one character, putchar() is better to use.

• putchar(): can only output a single character

• printf(): can output various types of data, such as %d %f %lf %s can be used
