10 Array programs in C

Unleashing the Power of Arrays in C: 10 Essential Programs! 💪🔢

Arrays, the superheroes of C programming, bring versatility to your code. Let's explore 10 crucial programs to master array manipulation!

1. Array Declaration and Initialization 🌐

c
#include <stdio.h>

int main() {
    // Declare and initialize an array
    int numbers[5] = {1, 2, 3, 4, 5};

    // Access and print array elements
    for (int i = 0; i < 5; ++i) {
        printf("%d ", numbers[i]);
    }

    return 0;
}

Understanding how to declare, initialize, and access array elements is the first step!

2. Sum of Array Elements ➕

c
#include <stdio.h>

int main() {
    int numbers[] = {10, 20, 30, 40, 50};
    int sum = 0;

    // Calculate the sum of array elements
    for (int i = 0; i < 5; ++i) {
        sum += numbers[i];
    }

    printf("Sum: %d\n", sum);
    return 0; 
}

Learn to iterate through an array and perform operations like calculating the sum!

3. Finding the Largest Element 📈

c
#include <stdio.h> 
int main() {
    int numbers[] = {12, 45, 78, 23, 56};
    int max = numbers[0];

    // Find the largest element in the array
    for (int i = 1; i < 5; ++i) {
        if (numbers[i] > max) {
            max = numbers[i];
        }
    }

    printf("Largest Element: %d\n", max);
    return 0;
 }

Uncover the technique to identify the largest element within an array!

4. Reversing an Array 🔁

c
#include <stdio.h>

int main() {
    int numbers[] = {1, 2, 3, 4, 5};
    
    // Reverse the array
    for (int i = 4; i >= 0; --i) {
        printf("%d ", numbers[i]);
    }

    return 0;
}

Master the art of reversing the order of elements in an array!

5. Searching for an Element 🔍

c
#include <stdio.h>

int main() {
    int numbers[] = {10, 20, 30, 40, 50};
    int target = 30;
    int found = 0;

    // Search for an element in the array
    for (int i = 0; i < 5; ++i) {
        if (numbers[i] == target) {
            found = 1;
            break;
        }
    }

    printf("Element %d %s\n", target, found ? "found" : "not found");
    return 0;
}

Unlock the secret to locating a specific element in an array!

6. Copying an Array 📝

c
#include <stdio.h>

int main() {
    int source[] = {2, 4, 6, 8, 10};
    int destination[5];

    // Copy elements from source to destination
    for (int i = 0; i < 5; ++i) {
        destination[i] = source[i];
    }

    // Print the copied array
    for (int i = 0; i < 5; ++i) {
        printf("%d ", destination[i]);
    }

    return 0;
}

7. Merging Two Arrays 🔄

c
#include <stdio.h>

int main() {
    int arr1[] = {1, 2, 3};
    int arr2[] = {4, 5, 6, 7};
    int merged[7];

    // Merge two arrays
    int i, j;
    for (i = 0; i < 3; ++i) {
        merged[i] = arr1[i];
    }

    for (j = 0; j < 4; ++j) {
        merged[i + j] = arr2[j];
    }

    // Print the merged array
    for (int k = 0; k < 7; ++k) {
        printf("%d ", merged[k]);
    }

    return 0;
}

Discover the technique to combine the elements of two arrays into a new one!

8. Removing Duplicates from an Array 🚫

c
#include <stdio.h>

int main() {
    int numbers[] = {1, 2, 2, 3, 4, 4, 5};
    int n = 7;

    // Remove duplicates from the array
    for (int i = 0; i < n; ++i) {
        for (int j = i + 1; j < n; ) {
            if (numbers[j] == numbers[i]) {
                for (int k = j; k < n; ++k) {
                    numbers[k] = numbers[k + 1];
                }
                --n;
            } else {
                ++j;
            }
        }
    }

    // Print the array without duplicates
    for (int i = 0; i < n; ++i) {
        printf("%d ", numbers[i]);
    }

    return 0;
}

Learn the process of eliminating duplicate elements from an array!

9. Sorting an Array 📊

c
#include <stdio.h>

int main() {
    int numbers[] = {5, 2, 9, 1, 5, 6};
    int n = 6;

    // Sort the array in ascending order
    for (int i = 0; i < n - 1; ++i) {
        for (int j = 0; j < n - i - 1; ++j) {
            if (numbers[j] > numbers[j + 1]) {
                // Swap if the element found is greater
                int temp = numbers[j];
                numbers[j] = numbers[j + 1];
                numbers[j + 1] = temp;
            }
        }
    }

    // Print the sorted array
    for (int i = 0; i < n; ++i) {
        printf("%d ", numbers[i]);
    }

    return 0;
}

10. 2D Array Magic ✨

c
#include <stdio.h>

int main() {
    int matrix[3][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};

    // Access and print elements of a 2D array
    for (int i = 0; i < 3; ++i) {
        for (int j = 0; j < 3; ++j) {
            printf("%d ", matrix[i][j]);
        }
        printf("\n");
    }

    return 0;
}
