Explain Input Output Statements in C
Question
Explain Input Output Statements in C
Solution
Input and output statements in C are used to read and write data from and to standard input and output devices. They are part of the standard library and are defined in the stdio.h header file.
-
Input Statements in C: The most commonly used input function in C is
scanf(). This function reads the input from the standard input device (keyboard). The syntax of thescanf()function isscanf("format specifiers", list of addresses of variables);. For example, to read an integer value from the user, you can usescanf("%d", &num);where%dis the format specifier for integer. -
Output Statements in C: The most commonly used output function in C is
printf(). This function writes the output to the standard output device (screen). The syntax of theprintf()function isprintf("format specifiers", list of variables);. For example, to print an integer value, you can useprintf("%d", num);where%dis the format specifier for integer.
Remember, the format specifiers in the scanf() and printf() functions should match with the type of variable that you want to read or print. For example, use %d for integers, %f for floating point numbers, %c for characters, and %s for strings.
