用C打印2D数组 [英] Printing a 2D array in C

问题描述

我将如何使用scanf在c 中使用用户输入的二维打印数组，名为grid [] []和for循环的数组?

how would I print a 2d array in c using scanf for user input, array called grid[ ][ ] and a for loop?

假设用户输入3 5，则输出将为:

say if the user types in 3 5, the output will be:

.....
.....
.....

这是我到目前为止编写的代码(这里是新手):

Here is the code that I have written so far (newbie here):

#include <stdio.h>

#define MAX 10

int main()
{
    int grid[MAX][MAX];
    int row, col;
    int i,j;

    printf("Please enter your grid size: ");
    scanf("%d %d", &row, &col);

    for (i=0; i<MAX; i++)
        for //i gave up here


}

这只是我整个任务阶段的一小部分:

This is only a little part of the whole stage of my task:

Enter number of rows and columns followed by list of words (hit enter twice to end list): 10 15
quick
brown
fox
jumped
over
lazy
dog

  0. quick
  1. brown
  2. fox
  3. jumped
  4. over
  5. lazy
  6. dog

允许并应该包含在代码中的函数:字符串函数-strlen()，strcpy()，strcat()，strchr()，strcmp()，strstr()

functions allowed and should be included in the code: string functions - strlen(),strcpy(), strcat(), strchr(), strcmp(),strstr()

必须使用2d数组

必须使用fgets作为单词.输出必须匹配确切的格式.

must use fgets for words. Out put must match the exact format.

推荐答案

这有帮助吗?

#include <stdio.h>

#define MAX 10

int main()
{
    char grid[MAX][MAX];
    int i,j,row,col;

    printf("Please enter your grid size: ");
    scanf("%d %d", &row, &col);


    for (i = 0; i < row; i++) {
        for (j = 0; j < col; j++) {
            grid[i][j] = '.';
            printf("%c ", grid[i][j]);
        }
        printf("\n");
    }

    return 0;
}
