Float:

In C, the float data type is used to represent floating-point numbers, which are real numbers with a decimal point. It is one of the primary data types and is commonly used for variables that store values with fractional parts. The float type typically occupies 4 bytes in memory.

Example:

#include <stdio.h>

int main() {
    // Declaration and initialization of float variables
    float num1 = 3.14;
    float num2 = -2.5;
    float sum, product;

    // Performing arithmetic operations
    sum = num1 + num2;
    product = num1 * num2;

    // Displaying the values and results
    printf(“Number 1: %fn”, num1);
    printf(“Number 2: %fn”, num2);
    printf(“Sum: %fn”, sum);
    printf(“Product: %fn”, product);

    return 0;
}

 

Output:

Number 1: 3.140000
Number 2: -2.500000
Sum: 0.640000
Product: -7.850000

Explanation of code:

• #include <stdio.h>: This line includes the standard input-output library for functions like printf.
• int main(): The main function, where the program execution begins.
• float num1 = 3.14; and float num2 = -2.5;: Declaration and initialization of float variables.
• float sum, product;: Declaration of two more float variables without initialization.
• sum = num1 + num2; and product = num1 * num2;: Performing arithmetic operations.
• printf(“Number 1: %fn”, num1);: Printing the value of num1 using the %f format specifier.
• Similarly, the values of num2, sum, and product are printed using printf.
• return 0;: Indicates successful program execution.
