Go Program to Check Two Matrixes are Equal

In Go programming, we can use the equals operator to check the two matrixes are equal or not. This Go program allows users to enter the two matrixes, size, and items. Next, we used the if else statement (if firstMat == secondMat) to check whether they are equal or not.

package main

import "fmt"

func main() {
    var i, j, rows, columns int

    var firstMat [10][10]int
    var secondMat [10][10]int

    fmt.Print("Enter the Matrix rows and Columns = ")
    fmt.Scan(&rows, &columns)

    fmt.Println("Enter the First Matrix Items = ")
    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            fmt.Scan(&firstMat[i][j])
        }
    }
    fmt.Println("Enter the Second Matrix Items = ")
    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            fmt.Scan(&secondMat[i][j])
        }
    }
    if firstMat == secondMat {
        fmt.Println("The First Matrix and the Second Matrix are Equal")
    } else {
        fmt.Println("The First Matrix is Not Equal to the Second Matrix")
    }
}

The First Matrix and the Second Matrix are Equal

Golang Program to Check Two Matrixes are Equal.

In this Go example, the nested for loop iterate the matrix items. Within the loop, the if statement (if firstMat[i][j] != secondMat[i][j]) checks each item of the first matrix is not equal to the second matrix. If True, assign zero to the isequal variable. Finally, we used if-else to check matrices are equal or not.

package main

import "fmt"

func main() {
    var i, j, rows, columns int

    var firstMat [10][10]int
    var secondMat [10][10]int

    fmt.Print("Enter the Matrix rows and Columns = ")
    fmt.Scan(&rows, &columns)

    fmt.Println("Enter the First Matrix Items = ")
    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            fmt.Scan(&firstMat[i][j])
        }
    }
    fmt.Println("Enter the Second Matrix Items = ")
    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            fmt.Scan(&secondMat[i][j])
        }
    }
    isequal := 1
    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            if firstMat[i][j] != secondMat[i][j] {
                isequal = 0
                break
            }
        }
    }
    if isequal == 1 {
        fmt.Println("The First Matrix and the Second Matrix are Equal")
    } else {
        fmt.Println("The First Matrix is Not Equal to the Second Matrix")
    }
}

Enter the Matrix rows and Columns = 2 3
Enter the First Matrix Items = 
1 2 3
4 5 6
Enter the Second Matrix Items = 
1 2 3
4 5 6
The First Matrix and the Second Matrix are Equal

Go Program to find the two Matrixes are Equal or not using for loop range.

package main

import "fmt"

func main() {

    var firstMat [3][3]int
    var secondMat [3][3]int

    fmt.Println("Enter the First Matrix Items = ")
    for i, rows := range firstMat {
        for j := range rows {
            fmt.Scan(&firstMat[i][j])
        }
    }
    fmt.Println("Enter the Second Matrix Items = ")
    for i, rows := range secondMat {
        for j := range rows {
            fmt.Scan(&secondMat[i][j])
        }
    }
    isequal := 1
    for i, rows := range firstMat {
        for j := range rows {
            if firstMat[i][j] != secondMat[i][j] {
                isequal = 0
                break
            }
        }
    }
    if isequal == 1 {
        fmt.Println("The First Matrix and the Second Matrix are Equal")
    } else {
        fmt.Println("The First Matrix is Not Equal to the Second Matrix")
    }
