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,

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

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