Elements Of Rectangular Pyramid

C program to Use structure within union & display the contents of structure elements

#include

#include

void main()

{

struct student

{

char name[30];

char sex;

int rollno;

float percentage;

};

union details

{

struct student st;

}

union details

{

struct student st;

};

Union details set;

printf("Enter details:");

printf("\n Enter name:");

scanf("%s",set.st.name);

printf("\n Enter roll no:");

scanf("%d",&set.st.rollno);

flushall();

printf("\n Enter sex:");

scanf("%c",&set.st.sex);

printf("\n Enter percentage:");

scanf("%f",&set.st.percentage);

printf("\n The student details are:\n");

printf("\n Name : %s",set.st.name);

printf("\n Rollno :%d",set.st.rollno);

printf("\n Sex:%c",set.st.sex);

printf("\n Percentage %f",set.st.percentage);

getch();

}

Output

Enter details:

Enter name : Pritesh

Enter rollno: 10

Enter sex : m

Enter percentage: 89

The student details are:

Name : Pritesh

Rollno: 10

Sex : m

Percentage : 89.000000

C Program to print iterative rectangular pyramid

#include

#include 

int main()

{

    int number, row, col;

    int displayNum;

    printf("\nEnter Number of Rows to be display : \n");

    scanf("%d", &number);

     for (row = 1; row <= number; row++)

       {

        displayNum = 1;

        for (col = 1; col <= number; col++)

          {

            printf("%d\t", displayNum++);

        }

        printf("\n");

    }

    return 0;

}

Output

Enter Number of Rows to be display : 5

1    2    3    4    5    

1    2    3    4    5    

1    2    3    4    5    

1    2    3    4    5

C Program to print subtracting rectangular pyramid

#include

#include

int main()

  {

    int number, row, col;

    int displayNum;

    printf("\nEnter Number of Rows to be display : \n");

    scanf("%d", &number);

     for (row = 1; row <= number; row++)

     {

        displayNum = number;

        for (col = 1; col <= number; col++)

          {

            printf("%d\t", displayNum--);

        }

        printf("\n");

    }

     return 0;

}

Output

Enter Number of Rows to be display : 5

5    4    3    2    1
