C Program to perform Matrix Subtraction

Matrix Subtraction

We will write a C program to perform matrix subtraction operation.

Key points for subtraction of matrices

• Two matrices should be of same order (number of rows=number of columns).
• Subtract the corresponding element of matrices.

Example: Subtraction of matrix of order 3 * 3

Subtraction of Matrix (A-B) is as under:

A - B = C

C Program to perform Matrix Subtraction

Program Code:

#include<stdio.h>
int main()
{
 int A[3][3],B[3][3],C[3][3],i, j;
 //Loops for Reading A matrix
 for ( i = 0; i < 3; i++ ) //related to row
 {
   for ( j = 0; j < 3; j++ ) //related to column
   {
     printf("Matrix A[%d][%d]:",i,j);
     scanf("%d", &A[i][j]) ;
   }   
 }
 //Loops for Reading B matrix
 for ( i = 0; i < 3; i++ ) //related to row
 {
   for ( j = 0; j < 3; j++ ) //related to column
   {
     printf("Matrix B[%d][%d]:",i,j);
     scanf("%d", &B[i][j]) ;
   }   
 }
 printf("Matrix A is as under: \n") ;
 /* Print Matrix A, B */
 for ( i = 0; i < 3; i++ ) //related to row
 {
   for ( j = 0; j < 3; j++ ) //related to column
   {
     printf(" %d\t ",A[i][j] );
   }
   printf("\n");
 }
 printf("Matrix B is as under: \n") ;
 for ( i = 0; i < 3; i++ ) //related to row
 {
   for ( j = 0; j < 3; j++ ) //related to column
   {
     printf(" %d\t ",B[i][j] );
   }
   printf("\n");
 }
 printf("Matrix Subtraction is as under: \n");
 for ( i = 0; i < 3; i++ ) //related to row
 {
   for ( j = 0; j < 3; j++ ) //related to column
   {
     printf(" %d\t ",A[i][j] - B[i][j] );
   }
   printf("\n");
 }
 return 0;
}

Matrix A[0][0]:4
Matrix A[0][1]:5
Matrix A[0][2]:6
Matrix A[1][0]:7
Matrix A[1][1]:8
Matrix A[1][2]:9

Matrix B[1][0]:5
Matrix B[1][1]:4
Matrix B[1][2]:3
Matrix B[2][0]:2
Matrix B[2][1]:3
Matrix B[2][2]:6
Matrix A is as under:
 4        5       6
 7        8       9
 10       11      12
Matrix B is as under:
 1        3       2
 5        4       3
 2        3       6
Matrix Subtraction is as under:
 3        2       4
 2        4       6
 8        8       6

C program to find square of given number without an argument and a return value

C Programming => Functions

C program to find square of given number using function concept. This program demonstrate use of function without an argument and a return value.

Program code

#include<stdio.h>
int square(); //function prototype declaration.
int number; //use of global variable

int main()
{
  int answer;
  answer = square(); //Call function.
  printf("Square of %d is %d.", number, answer);
  return 0;
}

//User defined function to find square()
int square()
{
  printf("Enter your number:");
  scanf("%d", &number);
  //return answer to main function
  return(number*number);
}

Output of the program

Enter your number:5
Square of 5 is 25.

Program Code

#include<stdio.h>

int main()

{

  int number=100, sum=0;

  

  do{

    sum = sum + number;

    number = number + 1;

  }while(number<=200);

  printf("Sum of all numbers between 100 to 200:"); 

  printf(" %d", sum);

Flowchart to convert uppercase letters into lowercase

 RAPTOR Flowchart to convert Uppercase letters into Lowercase letters

Fig.: Flowchart to convert Uppercase letters into Lowercase letters

Note: 

• ASCII value of 'A' is 65, and 'a' is 97.
• If we add 32 into 65, we get 97 which is ASCII value of 'a'. 
• Hence we add 32 into 'chr' variable in the flowchart. This process we repeat up to 'Z' in the flowchart using loop.
