EXPERIMENT NO…… DATE ……………… …..
Aim : Write a program to find the occurrence of an element in the array. Code :
#include<stdio.h> void main() { int a[10],n,i,p,count=0; printf ("\nEnter the size of the array "); scanf("%d",&n); printf("\nEnter the elements into the array "); for(i=0;i<n;i++) { scanf("%d",&a[i]); } printf("\nEnter the element to find "); scanf("%d",&p); for(i=0;i<n;i++) { if(p==a[i]) count++; } printf("\nOccurence = %d\n",count); }
e1 | P a g
e2 | P a g
EXPERIMENT NO…… DATE …………… ……..
Aim : Write a program to find the sum of the numbers at even positions in the array. Code : #include<stdio.h> void main() { int a[10],n,i,sum=0; printf("\nEnter the size of the array "); scanf("%d",&n); printf("\nEnter the elements into the array "); for(i=0;i<n;i++) { scanf("%d",&a[i]); } for(i=0;i<n;i=i+2) { sum+=a[i]; } printf("\nSum of elements at even position = %d\n",sum); }
Output :
e4 | P a g
5 | P a g e
Output :
EXPERIMENT NO…… DATE …………… ……..
Aim : Write a program to insert a element into the array. Code : #include<stdio.h> void main() { int a[30], i, num, pos, el; printf("\nEnter no of elements :"); scanf("%d", &num); printf("\nEnter the elements"); //Read n elements in an array for (i = 0; i < num; i++) scanf("%d", &a[i]); printf("\nEnter element for insertion "); scanf("%d",&el); printf("\nEnter position for insertion "); scanf("%d",&pos); for(i=num;i>=pos;i--) { a[i+1]=a[i]; } a[pos]=el; num=num+1; printf("\nThe array is ");
7 | P a g e
8 | P a g e
EXPERIMENT NO…… DATE …………… ……..
Aim : Write a program to delete an element from the array. Code : #include<stdio.h> void main() { int a[30], i, num, pos; printf("\nEnter no of elements :"); scanf("%d", &num); printf("\nEnter the elements"); //Read n elements in an array for (i = 0; i < num; i++) scanf("%d", &a[i]); printf("\nEnter position for deletion "); scanf("%d",&pos); for(i=pos;i<num;i++) { a[i]=a[i+1]; } num=num-1; printf("\nThe array is "); for (i = 0; i < num; i++) printf("%d ", a[i]);
Output :
10 | P a g e
