Go Program to Find Sum of Each Matrix Column

Write a Go Program to Find the Sum of Each Matrix Column using the for loop. It allows entering the rows, columns, and matrix items. Next, it finds the sum of each column in a given matrix.

package main

import "fmt"

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

    var columnSumMat [10][10]int

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

    fmt.Println("Enter the Matrix Items to find the Columns Sum = ")
    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            fmt.Scan(&columnSumMat[i][j])
        }
    }

    for i = 0; i < rows; i++ {
        colsum := 0
        for j = 0; j < columns; j++ {
            colsum = colsum + columnSumMat[j][i]
        }
        fmt.Println("The Sum of Matrix Column Elements  = ", colsum)
    }
}

Enter the Matrix rows and Columns = 2 2
Enter the Matrix Items to find the Columns Sum = 
10 20
30 70
The Sum of Matrix Column Elements  =  40
The Sum of Matrix Column Elements  =  90

Golang Program to Find the Sum of Each Column in a Matrix using For loop range.

package main

import "fmt"

func main() {

    var columnSumMat [3][3]int

    fmt.Println("Enter the Matrix Items to find the Column Sum = ")
    for i, rows := range columnSumMat {
        for j := range rows {
            fmt.Scan(&columnSumMat[i][j])
        }
    }
    for i, rows := range columnSumMat {
        colsum := 0
        for j := range rows {
            colsum = colsum + columnSumMat[j][i]
        }
        fmt.Println("The Sum of Matrix Column Elements  = ", colsum)
    }
}
