C语言-稀疏数组转置

1.题目要求

2.代码实现 

#include <stdio.h>
#define MAX_TERM 80

// 定义稀疏矩阵结构体
typedef struct juzhen {
    int row;
    int col;
    int value;
} Juzhen;

// 显示稀疏矩阵
void show(Juzhen a[], int count_a) {
    printf(" i row col val\n");
    for (int i = 1; i <= count_a; i++) {
        printf(" %d|  %d   %d   %d\n", i, a[i].row, a[i].col, a[i].value);
    }
}

// 转置稀疏矩阵
void zhuanzhi(Juzhen a[], Juzhen b[]) {
    int i, j, k;
    b[0].row = a[0].col;
    b[0].col = a[0].row;
    b[0].value = a[0].value;
    if (a[0].value > 0) {
        k = 1;
        for (i = 0; i < a[0].col; i++) {
            for (j = 1; j <= a[0].value; j++) {
                if (a[j].col == i) {
                    b[k].row = a[j].col;
                    b[k].col = a[j].row;
                    b[k].value = a[j].value;
                    k++;
                }
            }
        }
    }
}

// 初始化稀疏矩阵
void init(Juzhen a[], int *rows, int *cols, int *count) {
    printf("please input the number of rows,cols and values\n");
    scanf("%d,%d,%d", rows, cols, count);
    a[0].row = *rows;
    a[0].col = *cols;
    a[0].value = *count;
    for (int i = 1; i <= *count; i++) {
    	printf("please input the row,col and value\n");
        scanf("%d,%d,%d", &a[i].row, &a[i].col, &a[i].value);
    }
}

int main() {
    Juzhen a[MAX_TERM];
    Juzhen b[MAX_TERM];
    int rows, cols, count;
    init(a, &rows, &cols, &count);
    show(a, count);
    printf("\n");
    zhuanzhi(a, b);
    show(b, count);
    return 0;
}
