Inputting Real Number

 Inputting Real Number

The field width of real numbers is not to be specified and therefore scanf() reads real numbers using the simple specification %f for both the notification.

Example:

Scanf(“%f%f”, &x, &y);

With input data 475.15 43.21 

Wi475.15 to x

43.21 to y

Example: write a program to take input of float number (prog5.c)

#include<stdio.h>

#include<conio.h>

void main()

{

float a,b;

clrscr();

printf("Enter two numbers");

scanf("%f%f",&a,&b);

printf("value of a=%f and b=%f",a,b);

getch();ll assign the values:

Output: entre two number of 12.15 

34.5555

Velue of a=540000 and b=34.555500

 Inputting character strings:

A scanf() function can input strings containing more than one

character.

Syntax:

%ws OR %wc

Here %c is used to read a single character.

 %s is used to read word.

Example:

Write a program for take input of character (prog4.c)

#include<stdio.h>

#include<conio.h>

void main()

{

char c;

clrscr();

printf("Enter character");

scanf("%c",&c);

printf("Inputted character is %c\t",c);

getch();

}

Output:

Enter character H

Inputing character is H 

Example:

Write a program for take input of string

#include<stdio.h>

#include<conio.h>

void main()

{

char c[20];

clrscr();

printf("Enter string");

scanf("%s",&c);

printf("Inputted string is \t %s",c);

getch();

}

Output:

Enter string heta 

Inputing string heta
