## C Program To Find Area and Perimeter of Square

### Algorithm

- Program Start
- Declare Variables
- Input side from the User
- Calculating Area of square
- Calculating Perimeter of square
- Display Result
- Program End

### Program

```
#include<stdio.h>
void main()
{
int side, aos, per;
printf("\nEnter the Length of Side : ");
scanf("%d", &side);
aos = side * side;
per = 4*side;
printf("Area of Square : %d", aos);
printf("Perimeter of Square : %d", per);
}
```

### Output

```
Enter the Length of Side : 6
Area of Square : 36
Perimeter of Square : 24
```

## C Program To Find Area and Perimeter of Square Using Function

### Algorithm

- Program Start
- Declare Variables
- Input side from the User
- Calling Function to calculate area of square
- Calculating Area of square
- Calling Function to calculate perimeter of square
- Calculating Perimeter of square
- Display Result
- Program End

### Program

```
#include<stdio.h>
void aos(int s)
{
int area;
area = s*s;
printf("Area of Square : %d", area);
}
void pos(int s)
{
int perimeter;
perimeter = 4*s;
printf("\nPerimeter of Square : %d",perimeter);
}
void main()
{
int side;
printf("\nEnter the Length of Side : ");
scanf("%d", &side);
aos(side);
pos(side);
}
```

### Output

```
Enter the Length of Side : 8
Area of Square : 64
Perimeter of Square : 32
```
