#include <stdio.h> #include <stdlib.h> int main(void) { int list= malloc(3sizeof(int)); if(list==NULL) { return 1; }

int i =0;
while (i<3)
{
    printf("Give a value: "); 
    scanf("%d",&list[i]);
    i++;
    printf("YES!\n");
}

int*tmp =malloc(4*sizeof(int));
if(tmp==NULL)
{
    free(list);
    return 1;
}

for(int i=0;i<3;i++)
{
    tmp[i]=list[i];
    printf("No!\n");
}

printf("Give a value: ");
scanf("%d",tmp[3]);
free(list);
list=tmp;

for(int i=0;i<4;i++)
{
    printf("%i\n",list[i]);
    printf("Why!\n");
}
free(list);
return 0;

Hello,

Your code is tagged C++ and C#. it is not C++,it is not C#, it is C language.

I suppose the line displayed int list= malloc(3sizeof(int)); is in fact int *list= malloc(3*sizeof(int));.

VScode needs a compiler, and that compiler must give a warning on the line scanf("%d",tmp[3]);.

The code you posted has multiple errors, mostly typographical, and will not compile. Therefore it makes no sense to discuss it not working. In the future, please copy and paste your code into the message and don't attempt to retype it.

After making what I thought were the obvious corrections, your the program executed perfectly. Assuming your code is similar to my corrections, you need to tell us why you think the code doesn't work. Be specific. Describe what you expected to happen and contrast that with what actually happened.
