C provides standard functions scanf() and printf(), to perform formatted inputs and outputs. These functions accept a format specification string and a variable list as the parameters. The format specification string is a character string that specifies the data type of each variable to be input or output and the size or width of the I/O. 1. Scanf The scanf() function is used for inputs formatted from standard inputs and provides numerous conversion options for the printf() function. scanf(format_specifiers, &data1, &data2,……); Example scanf('%d %c', &data1, &data2); 2. printf The printf() function is used for output formatted as the standard output according to a format specification. The format specification string and the output data are the parameters of the printf() function. Syntax: printf(format_specifiers, data1, data2,…..... ); Example: printf('%d %c', data1, data2); Here is a example program #include <stdio.h> void main(){ int a; printf('Enter a value:'); scanf('%d',&a); printf('Entered Value= %d',a); }
