One Dimensional Array Programs

Program to create an array of 10 integer. Enter values for 10 elements and display it.

#include<stdio.h>
#include<conio.h>
void main()
{
   int a[10],i;
   clrscr();
   printf("Enter Elements of Array:\n");
   for(i=0;i<10;i++)
   {
printf("Enter Value of a[%d]:",i);
scanf("%d",&a[i]);
   }
   printf("Elements of Array Are:\n");
   for(i=0;i<10;i++)
   {
printf("a[%d]:%d\n",i,a[i]);
   }
   getch();
}

Program to find sum of all the elements of array.

#include<stdio.h>
#include<conio.h>
void main()
{
   int a[10],i,sum=0;
   clrscr();
   printf("Enter Elements of Array:\n");
   for(i=0;i<10;i++)
   {
printf("Enter Value of a[%d]:",i);
scanf("%d",&a[i]);
sum=sum+a[i];
   }
   printf("Elements of Array Are:\n");
   for(i=0;i<10;i++)
   {
   printf("a[%d]:%d\n",i,a[i]);
   }
   printf("Sum of all element is %d:",sum);
   getch();
}

Output

Program to find maximum number from an array of 10 elements.

#include<stdio.h>
#include<conio.h>
void main()
{
int a[10],max,i;
clrscr();
for(i=0;i<10;i++)
{
   printf("Enter Value for A[%d]:",i);
   scanf("%d",&a[i]);
}
max=a[0];
for(i=1;i<10;i++)
{
   if(a[i]>max)
   max=a[i];
}
printf("Max=%d",max);
getch();
}

Output

Enter Value of a[0]: 23
Enter Value of a[1]: 45
Enter Value of a[2]: 12
Enter Value of a[3]: 05
Enter Value of a[4]: 47
Enter Value of a[5]: 67
Enter Value of a[6]: 89
Enter Value of a[7]: 99
Enter Value of a[8]: 10
Enter Value of a[9]: 20
Max=99

Program to arrange elements of an array in ascending order.

#include<stdio.h>
#include<conio.h>
#define N 10
void main()
{
int a[N],temp,i,j;
clrscr();
for(i=0; i<N; i++)
{
   printf(“Enter Element no %d: “,i+1);
   scanf(“%d”,&arr[i]);
}
for(i=1;i<N;i++)
{
for(j=0;j<N–i;j++)
   {
if(arr[j] >arr[j+1])
{
temp=arr[j];
arr[j]=arr[j+1];
arr[j+1]=temp;
   }
}
   }
   printf(“Sorted Array\n”);
   for(i=0;i<N;i++)
   {
printf(“ %d \n”,arr[i]);
   }
getch();
}

Output

Enter Element no 1: 23
Enter Element no 2: 74
Enter Element no 3: 11
Enter Element no 4: 34
Enter Element no 5: 55
Enter Element no 6: 67
Enter Element no 7: 89
Enter Element no 8: 56
Enter Element no 9: 99
Enter Element no 10:90
Sorted Array
11 23 34 55 56 67 74 89 90 99

Program to display ODD numbers from 1-D array.

#include<stdio.h>
#include<conio.h>
void main()
{
   int a[10],i;
   clrscr();
   printf("Enter Elements of Array:\n");
   for(i=0;i<10;i++)
   {
   printf("Enter Value of a[%d]:",i);
   scanf("%d",&a[i]);
}
printf("ODD Elements of Array Are:\n");
   for(i=0;i<10;i++)
   {
   if(a[i]%2!=0)
   printf("a[%d]:%d\n",i,a[i]);
   }
   getch();
}

Output

Enter Elements of Array:
Enter Value of a[0]:1 Enter Value of a[1]:2 Enter Value of a[2]:3 Enter Value of a[3]:4 Enter Value of a[4]:5 Enter Value of a[5]:6 Enter Value of a[6]:7 Enter Value of a[7]:8 Enter Value of a[8]:9 Enter Value of a[9]:10

   for(i=0;i<10;i++)
   {
printf("Enter Value of a[%d]:",i);
scanf("%d",&a[i]);
}
   printf("ODD Elements of Array Are:\n");
   for(i=0;i<10;i++)
   {
if(a[i]%2==0)
printf("a[%d]:%d\n",i,a[i]);
   }
