Developing Efficient Programs with C: Techniques and Examples

Program Code – Developing Efficient Programs with C: Techniques and Examples

#include <stdio.h>
#include <stdlib.h>

// Function Declaration
int* generatePrimeNumbers(int n);
int isPrime(int num);

int main() {
    int n;
    
    printf('Enter the number of prime numbers you want to generate: ');
    scanf('%d', &n);

    // Generate primes and store the return pointer in primesPtr
    int *primesPtr = generatePrimeNumbers(n);

    printf('First %d prime numbers are:
', n);
    for(int i = 0; i < n; i++) {
        printf('%d ', primesPtr[i]);
    }
    // Free the dynamically allocated memory
    free(primesPtr);
    
    return 0;
}

// Function to generate prime numbers
int* generatePrimeNumbers(int n) {
    int *primes = (int*)malloc(sizeof(int) * n);
    int count = 0; // Number of primes generated
    int num = 2;   // Number to check for primality

    while(count < n) {
        if(isPrime(num)) {
            primes[count] = num;
            count++;
        }
        num++;
    }
    
    return primes;
}

// Function to check if a number is prime
int isPrime(int num) {
    if (num <= 1) return 0; // 1 and less are not prime numbers
    for (int i = 2; i*i <= num; i++) {
        if (num % i == 0) return 0;
    }
    return 1;
}

Code Output:

Enter the number of prime numbers you want to generate: 5
First 5 prime numbers are:
2 3 5 7 11

Code Explanation:

At the heart of this example lies a simple but efficient program to generate the first n prime numbers, using basic principles of C programming.

The program starts by including the necessary headers for I/O operations and dynamic memory allocation. It then defines two crucial functions: generatePrimeNumbers, responsible for populating an array with the first n prime numbers; and isPrime, a helper function used to determine if a number is prime.

Execution begins in the main() function, where users are prompted to input the number of prime numbers they want to generate. Using dynamic memory allocation (malloc), generatePrimeNumbers creates an array large enough to hold n prime numbers. This optimization ensures we do not allocate more memory than required, sticking to the principle of efficient resource use.

The meat of this program is in the logic to find prime numbers. It runs a while loop that doesn’t stop until we have found n prime numbers. Inside the loop, it checks each number (num) for primality by calling isPrime(num). If a number is prime, it is added to the primes array and the count of found primes is increased. This continues until the array is filled with the first n primes.

The isPrime function implements a straightforward yet optimized algorithm for checking primality. It operates under the fact that a number is prime if it is not divisible by any number less than or equal to its square root. This reduces the number of divisions necessary to verify a prime, contributing to the program’s efficiency.

Lastly, the dynamically allocated memory for storing the prime numbers is freed before exiting the main function, ensuring no memory leaks. This program demonstrates managing dynamic memory, using functions, employing optimization techniques (like limiting the search space when checking for primality), and basic control structures in C.

Through its uncomplicated architecture, this program showcases how to achieve program efficiency. It harnesses the power of C to solve problems effectively, making it an excellent demonstration of developing efficient programs with C.
