1. Program to Generate a Series of 10 Natural Numbers

#include <stdio.h>
int main() {
    for (int i = 1; i <= 10; i++) {
        printf("%d ", i);
    }
    return 0;
}

2. Program to Generate a Series of Even Numbers from 2 to 20

#include <stdio.h>
int main() {
    for (int i = 2; i <= 20; i += 2) {
        printf("%d ", i);
    }
    return 0;
}

3. Program to Generate a Series of the First 10 Odd Numbers

#include <stdio.h>
int main() {
    for (int i = 1; i <= 20; i += 2) {
        printf("%d ", i);
    }
    return 0;
}

4. Program to Generate a Series: 5, 25, 125,... up to the 10th Term

#include <stdio.h>
int main() {
    int term = 5;
    for (int i = 1; i <= 10; i++) {
        printf("%d ", term);
        term *= 5;
    }
    return 0;
}

5. Program to Check if the Input Number is Odd or Even

#include <stdio.h>
int main() {
    int num;
    printf("Enter a number: ");
    scanf("%d", &num);
    
    if (num % 2 == 0) {
        printf("%d is even.\n", num);
    } else {
        printf("%d is odd.\n", num);
    }
    return 0;
}

6. Program to Check if an Entered Number is Positive, Negative, or Zero

#include <stdio.h>
int main() {
    int num;
    printf("Enter a number: ");
    scanf("%d", &num);
    
    if (num > 0) {
        printf("%d is positive.\n", num);
    } else if (num < 0) {
        printf("%d is negative.\n", num);
    } else {
        printf("The number is zero.\n");
    }
    return 0;
}

7. Program to Check if an Entered Number is Divisible by 3

#include <stdio.h>
int main() {
    int num;
    printf("Enter a number: ");
    scanf("%d", &num);
    
    if (num % 3 == 0) {
        printf("%d is divisible by 3.\n", num);
    } else {
        printf("%d is not divisible by 3.\n", num);
    }
    return 0;
}

Each of these programs serves its specific purpose and can be executed in any C compiler or IDE. Let me know if you have questions or need further explanations!
