C语言 萌新提问 矩阵赋值问题
设计一个简单的insert函数，用于给目标矩阵赋值，可是测试结果都不是想要的（通常是一个长的负数，如：-858993460）
希望大神可以帮帮忙
```#include
#define MAX 10
void initialize(int* size, int ar[]);
void insert(int max, int* size, int ar[], int num);
void iremove(int* size, int ar[], int num);
void display(int size, int ar[]);
int main()
{
int option = 0;
int num, ar[MAX];
int size = 0;
printf("Please select an option: \n");
printf("(1) 初始化 \n");
printf("(2) 插入一个int \n");
printf("(3) 移除一个intr \n");
printf("(4) 展示所有矩阵整数 \n");
printf("(5) 推出 \n");
do {
printf("请选择: \n");
scanf("%d", &option);
switch (option) {
case 1:
initialize(&size, ar);
break;
case 2:
printf("输入一个要添加的整数: \n");
scanf("%d", &num);
insert(MAX, &size, ar, num);
break;
case 3:
printf("输入一个要被移除的整数: \n");
scanf("%d", &num);
iremove(&size, ar, num);
break;
case 4:
display(size, ar);
break;
default:
break;
}
} while (option < 5);
return 0;
}
void display(int size, int ar[])
{
int i;
printf("矩阵中有%d个数，分别为 : \n", size);
for (i = 0; i < size; i++)
printf("%d ", ar[i]);
printf("\n");
}
void initialize(int* size, int ar[])
{
int total, i, num;
printf("请输入输入的整数数量 (MAX=%d): \n", MAX);
scanf("%d", &total);
(*size) = 0;
printf("Enter the integers: \n");
for (i = 0; i < total; i++) {
scanf("%d", &num);
insert(MAX, size, ar, num);
}
}
void insert(int max, int* size, int ar[], int num)
{
/* Write your code here /
static count = 0;
if (*size >= max) {
printf("矩阵已满l\n");
}
else {
//printf("*size=%d, num=%d", *size, num);
ar[*size] = num;
(*size)++;
//printf("Stored, %d target=%d\n", ar[(size-1)], num);
//display(*size, ar);
}
int i, j, key;
for (j = 0;j < (*size) + 1;j++) {
i = j - 1;
key = ar[j];
while (i >= 0 && ar[i] > key) {
ar[i + 1] = ar[i];
i--;
}
ar[i + 1] = key;
}
}
void iremove(int* size, int ar[], int num)
{
if (*size == 0) printf("矩阵是空的\n");
else {
int i, j;
for (i = j = 0; ar[i] != '\0'; ++i) {
if (ar[i] != num) {
ar[j++] = ar[i];
}
}
ar[j] = '\0';
if (j == i) printf("没找到");
}
}
