Here is a step-by-step guide to solve the problem in C: 1. First, you need to include the necessary header files. In this case, you need `stdio.h` for input/output functions. ```c #include ``` 2. Declare a `char` variable to store the data type identifier and a `void*` pointer to store the value. ```c char type; void *value; ``` 3. Use `scanf` to get the data type identifier from the user. ```c scanf("%c", &type); ``` 4. Use a `switch` statement to handle different data types. If the identifier is 'i', allocate memory for an `int` and read an integer from the user. If the identifier is 'f', allocate memory for a `float` and read a float from the user. For any other identifier, print "Invalid type entered!" and exit the program. ```c switch (type) { case 'i': value = malloc(sizeof(int)); scanf("%d", (int*)value); break; case 'f': value = malloc(sizeof(float)); scanf("%f", (float*)value); break; default: printf("Invalid type entered! "); return 0; } ``` 5. Use another `switch` statement to print the value with the appropriate label. If the identifier is 'i', print "Integer: " followed by the integer value. If the identifier is 'f', print "Float: " followed by the float value, rounded off to two decimal places. ```c switch (type) { case 'i': printf("Integer: %d ", *(int*)value); break; case 'f': printf("Float: %.2f ", *(float*)value); break; } ``` 6. Finally, free the allocated memory and return 0 to indicate successful termination of the program. ```c free(value); return 0; ``` Remember to compile and run your program to make sure it works as expected.

Question

Here is a step-by-step guide to solve the problem in C:

1. First, you need to include the necessary header files. In this case, you need `stdio.h` for input/output functions.

```c
#include <stdio.h>
```

2. Declare a `char` variable to store the data type identifier and a `void*` pointer to store the value.

```c
char type;
void *value;
```

3. Use `scanf` to get the data type identifier from the user.

```c
scanf("%c", &type);
```

4. Use a `switch` statement to handle different data types. If the identifier is 'i', allocate memory for an `int` and read an integer from the user. If the identifier is 'f', allocate memory for a `float` and read a float from the user. For any other identifier, print "Invalid type entered!" and exit the program.

```c
switch (type) {
    case 'i':
        value = malloc(sizeof(int));
        scanf("%d", (int*)value);
        break;
    case 'f':
        value = malloc(sizeof(float));
        scanf("%f", (float*)value);
        break;
    default:
        printf("Invalid type entered!
");
        return 0;
}
```

5. Use another `switch` statement to print the value with the appropriate label. If the identifier is 'i', print "Integer: " followed by the integer value. If the identifier is 'f', print "Float: " followed by the float value, rounded off to two decimal places.

```c
switch (type) {
    case 'i':
        printf("Integer: %d
", *(int*)value);
        break;
    case 'f':
        printf("Float: %.2f
", *(float*)value);
        break;
}
```

6. Finally, free the allocated memory and return 0 to indicate successful termination of the program.

```c
free(value);
return 0;
```

Remember to compile and run your program to make sure it works as expected.
