How to count the Number of Occurrences of Specified Element in the Array in C - Step by Step Examples

How to count the Number of Occurrences of Specified Element in the Array in C ?

Answer

To count the number of occurrences of a specified element in an array in C, you can use loops to iterate through the array and count each occurrence.


✐ Examples

1 Count Occurrences of Element 30 in Integer Array using loop

In this example,

  1. We create an integer array named numbers with values 10, 20, 30, 40, 30, 50.
  2. We initialize a counter variable count to 0 to store the count of occurrences.
  3. We use a loop to iterate through the array and increment count each time element 30 is found.
  4. After the loop, count will contain the total count of occurrences of element 30.

C Program

#include <stdio.h>
int main() {
    int numbers[] = {10, 20, 30, 40, 30, 50};
    int count = 0;
    for(int i = 0; i < sizeof(numbers) / sizeof(numbers[0]); i++) {
        if(numbers[i] == 30) {
            count++;
        }
    }
    printf("Number of occurrences of element 30: %d", count);
    return 0;
}

Output

Number of occurrences of element 30: 2

2 Count Occurrences of Element 'banana' in String Array using loop

In this example,

  1. We create a character array named fruits with values 'a', 'b', 'b', 'a', '\0'.
  2. We initialize a counter variable count to 0 to store the count of occurrences.
  3. We use a loop to iterate through the array and increment count each time character 'b' is found.
  4. After the loop, count will contain the total count of occurrences of character 'b'.

C Program

#include <stdio.h>
int main() {
    char fruits[] = {'a', 'b', 'b', 'a', '\0'};
    int count = 0;
    for(int i = 0; fruits[i] != '\0'; i++) {
        if(fruits[i] == 'b') {
            count++;
        }
    }
    printf("Number of occurrences of element 'b': %d", count);
    return 0;
}

Output

Number of occurrences of element 'b': 2
