Initialisation of one-dimensional array

• In C, you can initialize a one-dimensional array at the time of declaration or later in your program.
• Here's how you can initialize an array:
Program.c
#include <stdio.h> int main() { // Initializing an integer array at the time of declaration int numbers[5] = {1, 2, 3, 4, 5}; // Accessing and printing array elements for (int i = 0; i < 5; ++i) { printf("Element at index %d: %d\n", i, numbers[i]); } return 0; }

Output:
Element at index 0: 1
Element at index 1: 2
Element at index 2: 3
Element at index 3: 4
Element at index 4: 5


• In this example, the array numbers is declared and initialized with values {1, 2, 3, 4, 5}.
• Here's how you can initialize an array in another method:
Program.c
#include <stdio.h> int main() { // Declaring an integer array int numbers[5]; // Initializing array elements later in the program numbers[0] = 10; numbers[1] = 20; numbers[2] = 30; numbers[3] = 40; numbers[4] = 50; // Accessing and printing array elements for (int i = 0; i < 5; ++i) { printf("Element at index %d: %d\n", i, numbers[i]); } return 0; }
• In this second example, the array numbers is declared first, and then its elements are initialized later in the program. The loop is used to print the array elements.
