该程序假设以 3 x 3 板的方式显示用户输入的 9 个数字。然而,我得到的只是一些相当奇怪的数字。
我的disp_arr
功能有问题,但我只是不知道那里有什么错误。我对函数和指针相当陌生,但我想这就是我学习的方式!
这是我运行时得到的输出:2686636 clone errors
/* File: StudentID_Surname.c - e.g. 1234567_Wilson.c
* This program finds the range between highest and lowest value of a 2-D array */
#include <stdio.h>
#define NROW 3
#define NCOL 3
/* Write a function
void disp_arr(int a[NROW][NCOL]) { ... }
where a[][] is the 2-D array
Print the entire array to the screen. */
disp_arr( int temp );
int main(void)
{
/* declare needed variables or constants, e.g. */
int ar[NROW][NCOL];
int rows, cols;
int temp[9] = {1,2,3,4,5,6,7,8,9}; /* Storing 9 numbers */
/* prompt for the user to enter nine positive integers to be stored into the array */
int index = 0;
printf( "Please enter 9 positive integers :\n");
for ( rows = 0 ; rows < 3 ; rows++ )
{
for ( cols = 0 ; cols < 3 ; cols++ )
{
scanf( "%d", &ar[rows][cols] );
/* Store values in the temp[z] = {1 2 3 4 5 6 7 8 9}*/
temp[index] = ar[rows][cols];
index += 1; /* Increase the array in temp[z] */
}
}
/* Call disp_arr to display the 3 x 3 board */
disp_arr( temp );
}/* end main */
disp_arr( int storedValue )
{
int x,y;
for ( x = 0 ; x < 3 ; x++ )
{
for ( y = 0 ; y < 3 ; y++ )
{
printf( "%d\t", storedValue );
}
printf("\n");
}
}
我考虑过包括计数器,storedValue[counter]
但它返回更多错误=/
disp_arr( int storedValue )
{
int x,y;
int counter = 0
for ( x = 0 ; x < 3 ; x++ )
{
for ( y = 0 ; y < 3 ; y++ )
{
printf( "%d\t", storedValue[counter] );
counter += 1;
}
printf("\n");
}
}
任何帮助,将不胜感激。
提前致谢!
