Keil 5 is an integrated development environment (IDE) for embedded systems programming. It is commonly used for programming microcontrollers and other embedded devices. However, Keil 5 does not support the use of the "iostream" library, which is typically used for input and output operations in C++ programming.
Instead, Keil 5 provides its own library called "stdio.h" for standard input and output operations. You can use functions like "printf" and "scanf" from this library to perform input and output in your embedded C++ programs.
Here's an example of how you can use "stdio.h" for input and output in Keil 5:
```c
#include <stdio.h>
int main() {
int number;
printf("Enter a number: ");
scanf("%d", &number);
printf("You entered: %d\n", number);
return 0;
}
```
In this example, the program prompts the user to enter a number, reads the input using "scanf", and then displays the entered number using "printf".
