Solution
Here is a step-by-step guide to complete the program in C:
- First, include the necessary libraries. In this case, we need the standard input/output library.
#include <stdio.h>
- Declare the main function.
int main() {
- Declare the necessary variables. We need a character to store the data type identifier and a void pointer to store the value.
char type;
void *value;
- Prompt the user to enter the data type identifier and read it.
printf("Enter data type identifier (i for integer, f for float): ");
scanf("%c", &type);
- Depending on the entered identifier, prompt the user to enter the corresponding value and store it in the void pointer. Use a switch statement for this.
switch(type) {
case 'i': {
int *intValue = malloc(sizeof(int));
printf("Enter integer value: ");
scanf("%d", intValue);
value = intValue;
break;
}
case 'f': {
float *floatValue = malloc(sizeof(float));
printf("Enter float value: ");
scanf("%f", floatValue);
value = floatValue;
break;
}
default: {
printf("Invalid type entered!\n");
return 0;
}
}
- Print the entered value with the appropriate data type label.
switch(type) {
case 'i': {
printf("Integer: %d\n", *(int *)value);
break;
}
case 'f': {
printf("Float: %f\n", *(float *)value);
break;
}
}
- Free the allocated memory and return 0 to indicate that the program has finished successfully.
free(value);
return 0;
}
Please note that this program uses dynamic memory allocation to store the entered value. This is necessary because we don't know the size of the value at compile time.

The fundamental data types in c are int, float and char. Today, we're discussing int and float data types.The printf() function prints the given statement to the console. The syntax is printf("format string",argument_list);. In the function, if we are using an integer, character, string or float as argument, then in the format string we have to write %d (integer), %c (character), %s (string), %f (float) respectively.The scanf() function reads the input data from the console. The syntax is scanf("format string",argument_list);. For ex: The scanf("%d",&number) statement reads integer number from the console and stores the given value in variable .To input two integers separated by a space on a single line, the command is scanf("%d %d", &n, &m), where and are the two integers.TaskYour task is to take two numbers of int data type, two numbers of float data type as input and output their sum:Declare variables: two of type int and two of type float.Read lines of input from stdin (according to the sequence given in the 'Input Format' section below) and initialize your variables.Use the and operator to perform the following operations:Print the sum and difference of two int variable on a new line.Print the sum and difference of two float variable rounded to one decimal place on a new line.Input FormatThe first line contains two integers.The second line contains two floating point numbers.Constraints integer variables float variables Output FormatPrint the sum and difference of both integers separated by a space on the first line, and the sum and difference of both float (scaled to decimal place) separated by a space on the second line.Sample Input10 44.0 2.0Sample Output14 66.0 2.0ExplanationWhen we sum the integers and , we get the integer . When we subtract the second number from the first number , we get as their difference.When we sum the floating-point numbers and , we get . When we subtract the second number from the first number , we get as their difference.
