C programs to practice: Basic input and output handling

    Input is the data given the user to the program. Output is the response of the program to the user.

Let us create a program to handle basic input and output.

First, include the header file which has the definitions for functions definitions.

Next , identify the data type for basic input and outputs.

It has following types.

‘int’ -integer

‘float’ – float number.

‘double’ – double number.

‘char’ – character

‘short int’ -it is a short integer.

‘long int’ – it is a long integer.

To declare a variable, use the datatype with variable name.

To get the input ,use ‘scanf()’ function.

To display the output, use ‘printf()’ function.

Access specifiers:

It gives you the meaning of variable for getting the input and printing the output.

For eg, ‘%d’ is for integer values, ‘%f’ is for floating values and ‘%s’ is for string variables.

The operations for the variables, you can use arithmetic symbols.

Let us create the program.

C Program to handle basic input and output operations:

#include<stdio.h>

int main()

{

    int a,b,c=0;

    float d,e,f=0.0;

    char g[10];

    printf("Enter the two integer value");

    scanf("%d %d",&a,&b);

    printf("Enter the floating value");

    scanf("%f %f",&d,&e);

    printf("Enter your name");

    scanf("%s",g);

    c=a+b;

    f=d+e;

    printf(" The sum of two integer values are: %d",c);

    printf("\n The sum of two floating values are:%f",f );

    printf("\n Hi,%s ,Welcome to C world",g);

    return 0;

 }

Output:

Compile and run the program to get the output.
Enter the two integer value

4 5

Enter the floating value

5.6 6.7

Enter your name

rajeeva

The sum of two integer values are: 9

The sum of two floating values are:12.299999

 Hi,rajeeva ,Welcome to C world

This is the simple way of creating C program to handle basic input and output operations. Hope the code is useful to you. Keep coding!!!!
