Assignment No-1
Set A
1) write a C program to Count number of occurence
(or frequency) given sorted array.
Input = are []={1,1,2,2,2,2,3 3, x=2
output: 4/1/x (or 2) occurs & times in arr[]
#include<stdio.h>
void read(int a[], int n) {
int i;
for (i = 0; i < n; i++) {
printf("\nEnter the number: ");
scanf("%d", &a[i]);
}
}
void display(int a[], int n) {
int i;
for (i = 0; i < n; i++)
printf("%d\t", a[i]);
}
int count_occurrence(int a[], int n, int s) {
int i, count = 0;
for (i = 0; i < n; i++) {
if (a[i] == s) {
count++;
}
}
return count;
}
int main() {
int a[20], n, s, c;
printf("Enter how many elements in the array: ");
scanf("%d", &n);
read(a, n);
printf("\nArray elements are: ");
display(a, n);
printf("\nEnter search element: ");
scanf("%d", &s);
c = count_occurrence(a, n, s);
if (c == 0)
printf("\nSearch element not found");
else
printf("\nSearch element %d occurs %d times", s, c);
return 0;
}
Example Output:
Enter how many elements in the array: 9
Enter the number: 1
Enter the number: 1
Enter the number: 2
Enter the number: 2
Enter the number: 2
Enter the number: 2
Enter the number: 3
Enter the number: 3
Enter the number: 3
Array elements are: 1 1 2 2 2 2 3 3 3
Enter search element: 2
Q2. write a c program to accept n elements, Store
those elements and Store the Square of these
numbers in another array & display both the array
#include<stdio.h>
void read(int a[], int n) {
int i;
for (i = 0; i < n; i++) {
printf("\nEnter the number: ");
scanf("%d", &a[i]);
}
}
void display(int a[], int n) {
int i;
for (i = 0; i < n; i++) {
printf("%d\t", a[i]);
}
}
void square(int a[], int n, int b[]) {
for (int i = 0; i < n; i++) {
b[i] = a[i] * a[i];
}
}
int main() {
int a[20], b[20], n;
printf("\nEnter how many elements in the array: ");
scanf("%d", &n);
printf("\nEnter array elements:");
read(a, n);
square(a, n, b);
printf("\nFirst array: ");
display(a, n);
printf("\nSecond array (squares): ");
display(b, n);
return 0;
}
Example Output:
Enter how many elements in the array: 5
Enter the number: 1
Enter the number: 2
Enter the number: 3
Enter the number: 4
Enter the number: 5
First array: 1 2 3 4 5
Second array (squares): 1 4 9 16 25
Q3 write a C program to copy one array into
another array
#include<stdio.h>
void read(int a[], int n) {
int i;
for (i = 0; i < n; i++) {
printf("\nEnter the number: ");
scanf("%d", &a[i]);
}
}
void display(int a[], int n) {
int i;
for (i = 0; i < n; i++) {
printf("%d\t", a[i]);
}
}
void copy(int a[], int n, int b[]) {
for (int i = 0; i < n; i++) {
b[i] = a[i]; // Copy elements from array a[] to b[]
}
}
int main() {
int a[20], b[20], n;
printf("\nEnter how many elements in the array: ");
scanf("%d", &n);
printf("\nEnter array elements:\n");
read(a, n);
copy(a, n, b);
printf("\nFirst array: ");
display(a, n);
printf("\nSecond array (copied): ");
display(b, n);
return 0;
}
Example Output:
Enter how many elements in the array: 5
Enter the number: 1
Enter the number: 2
Enter the number: 3
Enter the number: 4
Enter the number: 5
First array: 1 2 3 4 5
Second array (copied): 1 2 3 4 5
