Array in C Definition, Syntax, Working, Advantages & Disadvantages

Definition: Array is collection of similar data types. That means using array we can store similar type of elements.

In short array is a variable which can store multiple values. For example, if you want to store 100 and more intigers, then you need to create an array for it.

Syntax:

C Program to print Square of given Number using Function

Ex: Write a C program to print square of given number using function. How to write a C program to print square of given number using function. C program to print square of given number using function.

Input from user:

Enter the number: 4

Expected output:

Square of given number is= 16.0000

Step by Step logic of the given program:

1. First declare function give it meaningful name square().

2. Inside the main() accept input (number) from user declare varible say no.

3. Call the square() inside the printf() directly (It will print returned value means square of given number).

4. In the body of square() use simple logic of square which is-
Square=no*no;

5. After that return square.

C Program to print Square of given Number using Function:

#include<stdio.h>
float square(float);

int main()
{
float no;
printf("Enter the number: ");
scanf("%f",&no);

printf("Square of given number is= %f",square(no));
}
float square(float no)
{
float square=no*no;
return square;
}

Above program shows the following output:

C program to check given number is prime or not using function

Ex: Write a C program to check given number is prime or not using function. How to write a C program to check given number is prime or not using function. C program to check given number is prime or not using function.

Input from user:

Enter the number: 5

Expected output:

Given number is prime number.

Step by Step logic of the given program:

1. First declare function give it meaningful name prime().

2. Inside the main() accept input (number) from user declare varible say no.

3. Using if statement call prime function- if(prime(no)). after that inside the if statement print given number is prime otherwise print number is not prime. (If returned value is 1(true) then it will print number is prime otherwise it will execute else block.

4. After that inside the prime() we will use following prime numbers logic-
for(i=1;i<=no;i++)
{
if(no%i==0)
{
count++;
}
}

Here, count will be 2 only if number is prime.

5. In the last check count is 2 or not using- if(count==2)
If it's true return 1 otherwise return 0;

C program to check given number is prime or not using function:

#include<stdio.h>
int prime(int);
int main()
{
int no;

printf("Enter the number\n");
scanf("%d",&no);

if(prime(no))
{
printf("Given number is prime number");
}
else
{
printf("Given number is not prime number");
}
}
int prime(int no)
{
int count=0,i;

for(i=1;i<=no;i++)
{
if(no%i==0)
{
count++;
}
}
if(count==2)
{
return 1;
}
else
{
return 0;
}
}

Above program shows the following output:
