C Program – Clear ur Doubt

Hey there! Welcome to ClearUrDoubt.com. In this post, we will look at a C program to accept user input from the console and print it back on the console. Here is the C program:

/*
 This program written to accept input from the user 
 and print it back on the console.
*/
#include <stdio.h>

int main()
{
	// integer values
	int a;	
	printf("Enter a number: ");	             // ask user to enter a number
	scanf("%d", &a);	                     // read the user entered value
	
	/* if the user enters a value other than a number, 
	output will be unpredictabe. */
	printf("You have entered: %d.\n\n", a);	 // print it back on the console. 
	

	// floating point values
	float b;
	printf("Enter a floating point number: ");	  // ask user to enter a floating point number
	scanf("%f", &b);	                          // read the user entered value
	
	/* if the user enters a value other than a number, 
	output will be unpredictabe. */
	printf("You have entered: %f.\n", b);	                              // print it back on the console.
	printf("After considering only two decimal points: %.2f.\n\n", b);	  // print it back on the console using a CONTROL STRING.
	
	
	// char values
	int c[10];	
	printf("Enter a string: ");	             // ask user to enter some text
	scanf("%s", &c);	                     // read the user entered text
	
	/* Character array will read anything from user. 
	So, the output will be same as entered by the user. */
	printf("You have entered: %s.\n\n", c);	 // print it back on the console.
	
	return 0;
}
