Go 程序查找矩阵每行的总和

编写一个 Go 程序来查找矩阵每行的总和。它使用嵌套的 for 循环来查找给定矩阵中每一行的总和。

package main

import "fmt"

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

    var rowSumMat [10][10]int

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

    fmt.Println("Enter the Matrix Items to find the Row Sum = ")
    for i = 0; i < rows; i++ {
        for j = 0; j < columns; j++ {
            fmt.Scan(&rowSumMat[i][j])
        }
    }
    for i = 0; i < rows; i++ {
        sum := 0
        for j = 0; j < columns; j++ {
            sum = sum + rowSumMat[i][j]
        }
        fmt.Println("The Sum of Matrix ", i+1, " Row Elements  = ", sum)
    }
}

Enter the Matrix rows and Columns = 
2 2
Enter the Matrix Items to find the Row Sum = 
10 20
30 80
The Sum of Matrix  1  Row Elements  =  30
The Sum of Matrix  2  Row Elements  =  110

Golang 程序使用 For 循环范围查找矩阵每行的总和

package main

import "fmt"

func main() {

    var rowSumMat [3][3]int

    fmt.Println("Enter the Matrix Items to find the Row Sum = ")
    for i, rows := range rowSumMat {
        for j := range rows {
            fmt.Scan(&rowSumMat[i][j])
        }
    }
    for i, rows := range rowSumMat {
        sum := 0
        for j := range rows {
            sum = sum + rowSumMat[i][j]
        }
        fmt.Println("The Sum of Matrix ", i+1, " Row Elements  = ", sum)
    }
}
