This error message indicates that the function "scanf" has not been declared or defined in the current scope.
To fix this error, you need to include the necessary header file for the standard input/output library (stdio.h) at the beginning of your code.
For example:
```
#include <stdio.h>
int main() {
int num;
printf("Enter a number: ");
scanf("%d", &num);
printf("You entered: %d", num);
return 0;
}
```
If you have already included the header file, then check for any typos or syntax errors in your code that may be causing the issue.
