Data Input and Output Functions in C Programming
Data Input and output functions in C:
The C programming language supports many library functions which includes a number of input/output functions. These functions are used to transfer the information between the computer and device(user).
Some basic input/output functions are:
- scanf() and printf(): These two functions are used to transfer the single characters, strings and numerical values.
- getchar() and putchar(): These two functions are used to transfer single characters.
- gets() and puts(): is used to input and output strings.
1. How to use scanf and printf functions:
scanf() function is used to take input from user(keyboard).
printf() function is used to display output on the screen.
Example Program:
#include<stdio.h>
void main()
{
int num;// variable definition
/*Display message and ask user to enter some number... using printf()*/
printf("Enter the number:");
/*Read the number entered by user... using scanf()*/
scanf("%d",&num);
/*Display the number with message...using printf() */
printf("You entered number is: %d",num);
}
In above program %d is used to scan the intiger value.
If value is char then we use %c.
If value is float then we use %f and so on...
Above program shows the following output:
2. How to use getchar and putchar functions in our program:
getchar() function reads a single character from the terminal and returns it as an intiger.
putchar() function is used to display these single character.
Example program:
#include<stdio.h>
void main()
{
int a;
printf("Enter a character:");
/*Here, getchar function is used to store the accepted character in variable a*/
a = getchar();
/*Display the character stored in variable a using putchar function*/
putchar(a);
}
Above program shows the following output:
3. How to use gets() and puts() function in C:
In simple words:
gets() function is used to accept string from user.
puts() function is used to display the string.
Example program:
#include<stdio.h>
void main()
{
//Declare character array to store string
char str[100];
printf("Enter a string: ");
/*store string in array str*/
gets(str);
/*Display string on the output screen*/
puts(str);
}
Above program shows the following output:

C Program to Print Number Heart Pattern
Ex: Write a C program to print number heart pattern, which shows the steps to print pattern. How to write a C program to print number heart pattern, which shows steps to print pattern . C program to print number heart pattern which shows steps to print pattern.
Input from user:
Enter the number: 5
Expected output:
11 22
1111 2222
333333333
3333333
33333
333
3
This pattern is same as previous exercises star heart pattern.
Only difference is:
In this pattern we only need to replace the * with numbers 1, 2 and 3.
This number's also shows the steps to print this pattern.
Program to print number heart pattern:
#include<stdio.h>
void main()
{
int no,z;
int i,j,k;
printf("Enter the number:\n");
scanf("%d",&no);
/*To print upper part*/
z=no*2;
for(i=no/2;i<=no;i=i+2)
{
/*To print left peak */
for(j=1;j<no-i;j=j+2)
{
printf(" ");
}
for(k=1;k<=i;k++)
{
printf("1");
}
/*To print right peak*/
for(j=1;j<=no-i;j++)
{
printf(" ");
}
for(k=1;k<=i;k++)
{
printf("2");
}
printf("\n");
}
/*To print lower part means inverted triangle*/
for(i=1;i<=no;i++)
{
for(j=1;j<i;j++)
{
printf(" ");
}
for(k=1;k<z;k++)
{
printf("3");
}
z-=2;
printf("\n");
}
}
Above program shows the following output:
C Program to Print Diamond Number Pattern
Ex: Write a C program to print diamond number pattern. How to write a C program to print diamond number pattern. C program to print diamond number pattern.
Input from user:
Enter the number: 5
Expected output:
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
Step by step logic of the given:
For better understanding i have devided this code in two parts.
To print upper half part:
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1. Accept input number from user.
2. Run outer for loop from 1 to no which shows rows in pattern:
for(i=1;i<=no;i++)
3. Run inner for loop from i to no-1 to print spaces:
for(j=i;j<no;j++)
{
printf(" ");
}
4. Run another inner for loop from 1 to i which shows columns in pattern:
for(k=1;k<=i;k++)
5. Inside the second inner for loop print value of k with one space:
printf("%d ",k);
6. After that outside the block of inner for loop print next line \n for print new row.
To print lower half part:
1 2 3 4
1 2 3
1 2
1
1. Run outer loop from 1 to no-1 which shows rows in pattern:
for(i=1;i<no;i++)
2. Run inner for loop from 1 to i to print spaces:
for(j=1;j<=i;j++)
{
printf(" ");
}
3. Run another one inner for loop from 1 to no-i and inside the loop print value of k :
for(k=1;k<=no-i;k++)
{
printf("%d ",k);
}
4. Last print \n for new row.
Program to print diamond number pattern:
#include<stdio.h>
void main()
{
int no,i,j,k;
printf("Enter the number:");
scanf("%d",&no);
/*To print upper part*/
for(i=1;i<=no;i++)
{
for(j=i;j<no;j++)
{
printf(" ");
}
for(k=1;k<=i;k++)
{
printf("%d ",k);
}
/*For next row*/ printf("\n");
}
/*To print lower part*/
for(i=1;i<no;i++)
{
for(j=1;j<=i;j++)
{
printf(" ");
}
for(k=1;k<=no-i;k++)
{
printf("%d ",k);
}
/*For next row*/
printf("\n");
}
}
Above program shows the following output:
