Programming In C Practical 15
Question 1
Write a program to sort given array in ascending order.
Sort.cpp
C
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int arr[20],i,j,size,temp;
printf("\nEnter size of array: ");
scanf("%d",&size);
printf("\nEnter numbers in array: ");
for(i=0;i<size;i++)
{
printf("\nEnter number at arr[%d]:",i+1);
scanf("%d",&arr[i]);
}
for(i=0;i<size;i++)
{
for(j=0;j<size-i-1;j++)
{
if(arr[j]>arr[j+1])
{
temp=arr[j];
arr[j]=arr[j+1];
arr[j+1]=temp;
}
}
}
printf("\nSorted array is:");
for(i=0;i<size;i++)
{
printf("\narr[%d]: %d",i+1,arr[i]);
}
getch();
}
Output
Question 2
Write a C program to generate the output as follows:
4
4 3
4 3 2
4 3 2 1
Pattern.cpp
C
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int i,j;
for(i=4;i>=1;i--)
{
for(j=4;j>=i;j--)
{
printf("%d\t",j);
}
printf("\n");
}
getch();
}
Output
