Simple Searching in Array Example in C

About this program

This is an example program in c array example programs. Read the concept first: C Array, then study the code and output below.

Simple Searching In Array Example:

/*##Simple Searching In Array*/
/*##Searching Programs, Array Example Programs*/

#include  <stdio.h>
#define ARRAY_SIZE 5
 
int main()
{
    int numbers[ARRAY_SIZE], i ,search_key;

	// Read Input
    for (i = 0; i < ARRAY_SIZE; i++)
    {
		printf("Enter the Number : %d  : ", (i+1));
        scanf("%d", &numbers[i]);
    }
    
    printf("Enter the key\n");
    scanf("%d", &search_key);
    
    /*  Simple Search with Position */
	for (i = 0; i < ARRAY_SIZE; i++)
    {
		if(numbers[i] == search_key)
		{
			printf("Search Element Found . Position Is : %d \n",(i+1));
			break;
		}
		if(i == ARRAY_SIZE - 1)
		{
			printf("Search Element is not in Array.\n");
		}
    }
    
    
}

Sample Outputs:

Sample 1:

Enter the Number : 1  : 45
Enter the Number : 2  : 56
Enter the Number : 3  : 67
Enter the Number : 4  : 78
Enter the Number : 5  : 34
Enter the key
78
Search Element Found . Position Is : 4 

Sample 2:
Enter the Number : 1  : 45
Enter the Number : 2  : 67
Enter the Number : 3  : 48
Enter the Number : 4  : 35
Enter the Number : 5  : 78
Enter the key
23
Search Element is not in Array.

How It Works

This C program demonstrates Simple Searching in Array. It first reads the required values as input, then walks through the data with a loop to compute the result, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Read the input values that the program will work with.
3. Iterate over the data using a loop to apply the logic.
4. Use conditional statements to handle the different cases.
5. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
