In this tutorial you will learn about the C Program to check Matrix is an Identity Matrix and its application with practical example.
C Program to check Matrix is an Identity Matrix
In this tutorial, we will learn to create a C program that will check the Matrix is an Identity Matrix using C programming.
Prerequisites
Before starting with the tutorial, we assume that you are the best aware of the following C programming topics:
- Operators in C Programming.
- Basic Input and Output function in C Programming.
- Basic C programming.
- For loop in C programming.
Algorithm:-

1. Declaring the variables for the program. 2. Taking the input size of matrix. 3. Taking the input elements of matrix. 4. Checking the given Matrix is identity or not. 5. Printing the result. 6. End Program. |
Program to check the Matrix is an Identity Matrix:-
In this tutorial, we will check the matrix is the identity matrix or not with the help of the c programming. First, we will take the size and the elements of the matrix. Then we will check the matrix is an identity or not using the for loop and the conditional statements. Then will print the output to the user.

/* C Program to check Matrix is an Identity Matrix or Not */ #include<stdio.h> int main() { //Declaring the required variables for the program. int i, j, x, y, a[10][10], Flag = 1; //Taking the size of the multidimensional array printf("\n Please Enter Number of rows and columns : "); scanf("%d %d", &i, &j); //Taking the elements of the matrix printf("\n Please Enter the Matrix Elements \n"); for(x = 0; x < i; x++) { for(y = 0; y < j; y++) { scanf("%d", &a[x][y]); } } //Checking the matrix is identity or not for(x = 0; x < i; x++) { for(y = 0; y < j; y++) { if(a[x][y] != 1 && a[y][x] != 0) { Flag = 0; break; } } } //Printing the output result that matrix is identity or not. if(Flag == 1) { printf("\n The Matrix that you entered is an Identity Matrix "); } else { printf("\n The Matrix that you entered is Not an Identity Matrix "); } return 0; } |
Output:-
In the above program, we have first initialized the required variable.
- a[10][10]= it will hold the integer value.
- x = it will hold the integer value for the loop.
- y = it will hold the integer value for the loop.
- i= it will hold the input integer value for rows.
- j= it will hold the input integer value for columns.
Taking the size and the elements of the two matrices from the user.
Checking the Matrix is an Identity Matrix or not.
Printing the Matrix is an Identity Matrix or not.
