C program to find greatest among three integers

C program to find the greatest among three integers:

#include <stdio.h>
int main() {
  
  int num1, num2, num3;
 printf("Enter three integers: ");
    scanf("%d %d %d", &num1, &num2, &num3);

   if(num1 > num2 && num1 > num3) {
        printf("%d is the greatest.", num1);
    }
    else if(num2 > num1 && num2 > num3) {
        printf("%d is the greatest.", num2);
    }
    else {
        printf("%d is the greatest.", num3);
    }

    return 0;
}

In this program, we first declare three integer variables num1, num2, and num3. We then prompt the user to enter three integers using printf() and read those integers using scanf().

Next, we use a series of if and else if statements to compare the three numbers and determine which is the greatest. We use the logical operators && and || to combine conditions where necessary.

Finally, we print the result using printf().

Sample output :
The output of the program will depend on the values of the three integers entered by the user. Here's an example of what the output might look like for different inputs:

Example 1:
Enter three integers: 10 20 30
30 is the greatest.

Example 2:
Enter three integers: 20 10 20
20 is the greatest.

Example 3
Enter three integers: 5 5 5
5 is the greatest.

In Example 1, the greatest number is 30, so the program outputs "30 is the greatest." 

In Example 2, the greatest number is 20, so the program outputs "20 is the greatest."

 In Example 3, all three numbers are equal, so the program outputs "5 is the greatest."

Human Factors in Designing User-Centric Engineering Solutions

Human factors play a pivotal role in the design and development of user-centric engineering solutions. The integration of human-centered design principles ensures that technology not only meets functional requirements but also aligns seamlessly with users' needs, abilities, and preferences. This approach recognizes the diversity among users and aims to create products and systems that are intuitive, efficient, and enjoyable to use. In this exploration, we will delve into the key aspects of human factors in designing user-centric engineering solutions, examining the importance of user research, usability, accessibility, and the overall user experience. User Research: Unveiling User Needs and Behaviors At the core of human-centered design lies comprehensive user research. Understanding the target audience is fundamental to creating solutions that resonate with users. This involves studying user needs, behaviors, and preferences through various methodologies such as surveys, interview...

Introduction to C Programs

INTRODUCTION The programming language ‘C’ was developed by Dennis Ritchie in the early 1970s at Bell Laboratories. Although C was first developed for writing system software, today it has become such a famous language that a various of software programs are written using this language. The main advantage of using C for programming is that it can be easily used on different types of computers. Many other programming languages such as C++ and Java are also based on C which means that you will be able to learn them easily in the future. Today, C is mostly used with the UNIX operating system. Structure of a C program A C program contains one or more functions, where a function is defined as a group of statements that perform a well-defined task.The program defines the structure of a C program. The statements in a function are written in a logical series to perform a particular task. The most important function is the main() function and is a part of every C program. Rather, the execution o...

Performance

Performance ( Optional ) * The I/O system is a main factor in overall system performance, and can place heavy loads on other main components of the system ( interrupt handling, process switching, bus contention, memory access and CPU load for device drivers just to name a few. ) * Interrupt handling can be relatively costly ( slow ), which causes programmed I/O to be faster than interrupt driven I/O when the time spent busy waiting is not excessive. * Network traffic can also loads a heavy load on the system. Consider for example the sequence of events that occur when a single character is typed in a telnet session, as shown in figure( And the fact that a similar group of events must happen in reverse to echo back the character that was typed. ) Sun uses in-kernel threads for the telnet daemon, improving the supportable number of simultaneous telnet sessions from the hundreds to the thousands.   fig: Intercomputer communications. * Rather systems use front-end processor...
