Question

好的，所以大家好我试着制作一个程序，你可以猜到输入的数字随机放在矩阵或二维数组中。例如，用户输入了＆＃39; 3＆＃39;所以整数将放在矩阵的随机行和列上。

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>

#define R 4
#define C 4
void display(char a[][C]);
void placing(char b[][C]);
void guess(int m, int n);

void main(){
int x=0,y=0,m,n,number;
int matrix[R][C];
char a[R][C]={{'x','x','x','x'},{'x','x','x','x'},{'x','x','x','x'},{'x','x','x','x'}};
printf("\t\t\t      Welcome to my game");
printf("\nEnter your number: ");
scanf("%d",&number);
display(a);
placing(a);
printf("\n\nYour number is now being placed at a random location");
printf("\n\nGuess where your number is located (row) (column)");
printf("\n\nEnter coordinates: ");
scanf("%d%d",&m,&n);

getch();
}

void display(char a[][C]){
for(int row=0; row<R; row++)
{
    printf ("\n");
    for(int column=0; column<C; column++)
    {
    printf ("\t%c\t", a[row][column]);
    }
}
}

void placing(int b[][C]){
int randomrow=0,randomcolumn=0;
int i=0;

randomrow = rand()%4;
randomcolumn = rand()%4;

for(int row=0; row < randomrow; row++){
    for(int column=0;column < randomcolumn; column++, i++){
        b[row][column];
    }
}
printf("%d",b[R][C]);
}

这是整个计划。任何提示？

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
    int matrix[4][4] = 
    {
        {-1,-1,-1,-1},
        {-1,-1,-1,-1},
        {-1,-1,-1,-1},
        {-1,-1,-1,-1},
    };

    int user_input;
    int random_row;
    int random_column;
    int row_guess;
    int col_guess;

    printf("Enter a number to add: \n");
    scanf("%d", &user_input);
    printf("User entered: %d\n", user_input);

    srand(time(NULL)); 

    random_row = rand() % 4;
    random_column = rand() % 4;

    printf("random_row: %d\n", random_row);
    printf("random_column: %d\n", random_column);

    matrix[random_row][random_column] = user_input;

    for(int row = 0; row < 4; row++)
    {
        for(int column = 0; column < 4; column++)
        {
            printf("%d ", matrix[row][column]);
        }
        printf("\n");
    }

    printf("Guess Random Row: \n");
    scanf("%d", &row_guess);
    printf("User Row Guess: %d\n", row_guess);

    printf("Guess Random Column: \n");

    scanf("%d", &col_guess);
    printf("User Column Guess: %d\n", col_guess);

    if (matrix[row_guess][col_guess] == user_input)
    {
        printf("You guessed correctly!\n");
    }
    else
    {
        printf("You guessed incorrectly\n");
    }

    return 0;
}

将整数放置到二维数组（矩阵）
