Given Input:
int arr[5] = {2, 4, 6, 8, 10};
Enter the number you want to search for: 6
Expected Output:
The number 6 was found at index 2
Program:
#include <stdio.h>
int main() {
int arr[5] = {2, 4, 6, 8, 10};
int num, i, flag = 0;
printf("Enter the number you want to search for: ");
scanf("%d", &num);
for (i = 0; i < 5; i++) {
if (arr[i] == num) {
printf("The number %d was found at index %d\n", num, i);
flag = 1;
break;
}
}
if (flag == 0) {
printf("The number %d was not found in the array\n", num);
}
return 0;
}
Output:
Enter the number you want to search for: 8
The number 8 was found at index 3
Explanation:
This program initializes an array with 5 integers, then prompts the user to enter a number to search for. Using a for loop, the program checks each element of the array for a match with the user-entered number. If a match is found, the program prints the index of the match and sets a flag variable to 1. After the for loop, if the flag variable is still 0, the program prints that the number was not found in the array.
