C Programming Tutorial Exercises: A Comprehensive Solution Guide14

Welcome, aspiring programmers! This comprehensive guide provides detailed solutions to a wide range of exercises commonly found in introductory C programming tutorials. Whether you're a student working through a textbook, self-teaching, or simply looking to solidify your understanding, this resource aims to help you master the fundamentals of C. We'll cover various topics, providing explanations alongside the code, so you not only get the correct answer but also understand the underlying logic.

Note: This guide assumes a basic understanding of C syntax and concepts like variables, data types, operators, control flow (if-else, loops), functions, and arrays. If you're encountering fundamental difficulties, consider revisiting introductory materials before diving into these solutions.

Section 1: Basic Input/Output and Variables

Exercise 1: Write a program to print "Hello, World!" to the console.
#include
int main() {
printf("Hello, World!");
return 0;
}

Explanation: This utilizes the standard input/output library (stdio.h) and the `printf` function to display text on the console. `` adds a newline character for cleaner output.

Exercise 2: Write a program that takes two integer inputs from the user and prints their sum.
#include
int main() {
int num1, num2, sum;
printf("Enter two integers: ");
scanf("%d %d", &num1, &num2);
sum = num1 + num2;
printf("Sum: %d", sum);
return 0;
}

Explanation: `scanf` reads integer inputs from the user, storing them in `num1` and `num2`. The sum is calculated and then printed using `printf` with the `%d` format specifier for integers.

Section 2: Control Flow and Loops

Exercise 3: Write a program to check if a number is even or odd.
#include
int main() {
int num;
printf("Enter an integer: ");
scanf("%d", &num);
if (num % 2 == 0) {
printf("%d is even.", num);
} else {
printf("%d is odd.", num);
}
return 0;
}

Explanation: The modulo operator (%) gives the remainder after division. If the remainder when divided by 2 is 0, the number is even.

Exercise 4: Write a program to print the numbers from 1 to 10 using a `for` loop.
#include
int main() {
for (int i = 1; i
