Practice Question in Loops

💻Example:

//Odd Numbers 

#include <stdio.h>

int main() {
    
    int n;
    printf("Enter Number :");
    scanf("%d",&n);
    
    for(int i=1;i<=n;i++)
    {
        if(i%2==1)
        {
            printf("\n%d",i);
        }
    }
    
    return 0;
}

⚙️ Output :

Enter Number :5
1
3
5

💻Example:

// Even Numbers 
#include <stdio.h>

int main() {
    
    int n;
    printf("Enter Number :");
    scanf("%d",&n);
    
    for(int i=2;i<=n;i++)
    {
        if(i%2==0)
        {
            printf("\n%d",i);
        }
    }
    
    return 0;
}

⚙️ Output :

Enter Number :10
2
4
6
8
10

💻Example:

// Sum of  Numbers 
#include <stdio.h>

int main() {
    
    int n=3;
    
    printf("Enter Number :");
    scanf("%d",&n);
    
    int sum=0;
    
    for(int i=1;i<=n;i++)
    {
        sum=sum+i;
    }
    
    printf("Sum=%d",sum);
    
    return 0;
}

⚙️ Output :

Enter Number :10
Sum=55

💻Example:

// Factorial Of Numbers 
#include <stdio.h>

int main() {
    
    int n;
    printf("Enter Number :");
    scanf("%d",&n);
    
    int fact=1;
    
    for(int i=1;i<=n;i++)
    {
        fact=fact * i;
    }
    
    printf("Factorial=%d",fact);
    return 0;
}

⚙️ Output :

Enter Number :5
Factorial=120

💻Example:

#include <stdio.h>

int main() {
    
    int n;
    printf("Enter Number :");
    scanf("%d",&n);
    
    for(int i=1;i<=n;i++)
    {
        if(i%3==0 && i%5==0)
        {
            printf("\n%d is Divisible by both ",i);
        }
        else if (i%3==0 && i%5==0)
        {
            printf("\n%d is Divisible by 3 Or 5",i);
        }
        else
        {
            printf("\n%d is not Divisible by 3 Or 5",i);
        }
    }
    
    return 0;
}

⚙️ Output :

Enter Number :15
1 is not Divisible by 3 Or 5
2 is not Divisible by 3 Or 5
3 is not Divisible by 3 Or 5
4 is not Divisible by 3 Or 5
5 is not Divisible by 3 Or 5
6 is not Divisible by 3 Or 5
7 is not Divisible by 3 Or 5
8 is not Divisible by 3 Or 5
9 is not Divisible by 3 Or 5
10 is not Divisible by 3 Or 5
11 is not Divisible by 3 Or 5
12 is not Divisible by 3 Or 5
13 is not Divisible by 3 Or 5
14 is not Divisible by 3 Or 5
15 is Divisible by both
