Solution
Here is a step-by-step guide to solve the problem:
- First, you need to include the necessary header files. For this problem, you will need
stdio.hfor input/output functions.
#include <stdio.h>
- Declare a character variable to store the data type identifier and a union to store the integer or float value. A union is a special data type that allows you to store different types of data in the same memory location. You can define a union with many members, but only one member can contain a value at any given time.
char type;
union {
int i;
float f;
} value;
- Use
scanfto read the data type identifier and the corresponding value from the user.
scanf("%c", &type);
switch (type) {
case 'i':
scanf("%d", &value.i);
break;
case 'f':
scanf("%f", &value.f);
break;
default:
printf("Invalid type entered!\n");
return 0;
}
- Use a switch statement to print the entered value with the appropriate data type label. If the data type identifier is 'i', print the integer value. If it is 'f', print the float value rounded off to two decimal places. If it is any other character, print "Invalid type entered!".
switch (type) {
case 'i':
printf("Integer: %d\n", value.i);
break;
case 'f':
printf("Float: %.2f\n", value.f);
break;
default:
printf("Invalid type entered!\n");
}
- Finally, return 0 to indicate that the program has finished successfully.
return 0;
- Put it all together, your final code should look like this:
#include <stdio.h>
int main() {
char type;
union {
int i;
float f;
} value;
scanf("%c", &type);
switch (type) {
case 'i':
scanf("%d", &value.i);
break;
case 'f':
scanf("%f", &value.f);
break;
default:
printf("Invalid type entered!\n");
return 0;
}
switch (type) {
case 'i':
printf("Integer: %d\n", value.i);
break;
case 'f':
printf("Float: %.2f\n", value.f);
break;
default:
printf("Invalid type entered!\n");
}
return 0;
}
This program will correctly handle integer and float values, and will print an error message for any other data type identifier.

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.
