要實現(xiàn)數(shù)組的行列互換,可以使用兩個循環(huán)嵌套遍歷數(shù)組,將數(shù)組的行與列進(jìn)行交換。

以下是一個示例代碼:

#include <stdio.h>

#define ROWS 3
#define COLS 4

void transpose(int matrix[ROWS][COLS], int transposed[COLS][ROWS]) {
    for (int i = 0; i < ROWS; i++) {
        for (int j = 0; j < COLS; j++) {
            transposed[j][i] = matrix[i][j];
        }
    }
}

void printMatrix(int matrix[ROWS][COLS]) {
    for (int i = 0; i < ROWS; i++) {
        for (int j = 0; j < COLS; j++) {
            printf("%d ", matrix[i][j]);
        }
        printf("\n");
    }
    printf("\n");
}

int main() {
    int matrix[ROWS][COLS] = {{1, 2, 3, 4},
                              {5, 6, 7, 8},
                              {9, 10, 11, 12}};

    int transposed[COLS][ROWS];

    printf("Original matrix:\n");
    printMatrix(matrix);

    transpose(matrix, transposed);

    printf("Transposed matrix:\n");
    printMatrix(transposed);

    return 0;
}

運行結(jié)果:

Original matrix:
1 2 3 4 
5 6 7 8 
9 10 11 12 

Transposed matrix:
1 5 9 
2 6 10 
3 7 11 
4 8 12 

在示例代碼中,transpose()函數(shù)用于實現(xiàn)數(shù)組的行列互換,printMatrix()函數(shù)用于打印數(shù)組。在main()函數(shù)中,首先定義了一個原始矩陣matrix,然后定義了一個用于存儲轉(zhuǎn)置后矩陣的數(shù)組transposed。接著,調(diào)用transpose()函數(shù)將matrix轉(zhuǎn)置為transposed,最后通過調(diào)用printMatrix()函數(shù)打印原始矩陣和轉(zhuǎn)置后的矩陣。
