How to check if Specified Element is present in the Array in C


How to check if Specified Element is present in the Array in C ?

Answer

To check if a specified element is present in an array in C, you can use a loop to iterate through the array and compare each element.



✐ Examples

1 Check if Element 30 is present in Integer Array

In this example,

  1. We create an integer array named numbers with values 10, 20, 30, 40, 50.
  2. We use a for loop to iterate through the array and compare each element with the specified element 30.
  3. If the element is found, we set a boolean variable found to true; otherwise, it remains false.

C Program

#include <stdio.h>
int main() {
    int numbers[] = {10, 20, 30, 40, 50};
    int size = sizeof(numbers) / sizeof(numbers[0]);
    int element = 30;
    int found = 0;
    for (int i = 0; i < size; ++i) {
        if (numbers[i] == element) {
            found = 1;
            break;
        }
    }
    printf("Element 30 is present: %s\n", found ? "true" : "false");
    return 0;
}

Output

Element 30 is present: true

2 Check if Element 'banana' is present in String Array

In this example,

  1. We create a string array named fruits with values 'apple', 'banana', 'cherry'.
  2. We use a for loop to iterate through the array and compare each element with the specified element 'banana'.
  3. If the element is found, we set a boolean variable found to true; otherwise, it remains false.

C Program

#include <stdio.h>
#include <string.h>
int main() {
    char *fruits[] = {"apple", "banana", "cherry"};
    int size = sizeof(fruits) / sizeof(fruits[0]);
    char *element = "banana";
    int found = 0;
    for (int i = 0; i < size; ++i) {
        if (strcmp(fruits[i], element) == 0) {
            found = 1;
            break;
        }
    }
    printf("Element 'banana' is present: %s\n", found ? "true" : "false");
    return 0;
}

Output

Element 'banana' is present: true
