## Programs in C

(in Turbo C)

#### Snippets-3

Program 13: Write a program in C, which can take an integer number 'num' whose value is 300 and then find the value of (num * num ) / num.

Program taking integer from the user & calculating (num*num)/num

```#include <stdio.h>
#include <conio.h>
main()
{
int num;
clrscr();
num = 300;
printf("\n %d * %d / %d = %d",num,num,num,(num*num)/num);
getch();
}
```

Program 14: Write a program in C, which can take an integer number greater than 127 and then print it into character form using %c program taking integer >127 and print equivalent character

```#include <stdio.h>
#include <ctype.h>

main()
{
int num;
clrscr();

printf(" Enter the number > 127 : ");
scanf("%d",&num);
printf("\n The character equvilant of %d is %c",num,num);
getch();
}
```

Program 15: Write a program in C, which can take radius of a circle and then calculate the area of the circle. Using the same radius also calculate the volume of sphere [ take PI = 3.14].
Program takes radius as input & calculates the area.

```#include <stdio.h>
#include <conio.h>

main()
{

clrscr();

pi=3.14;
getch();
}
```

Program 16: Write a program in ‘C’, which can take an integer number num from the user and calculate maths functions  i.e. sin(num), cos(num) and log(num). Program takes an integer number as input  and calculate sin(num),cos(num), log(num)

```#include <stdio.h>
#include <math.h>
#include <conio.h>

int main()
{
float num;

clrscr();
printf("Enter the number : ");
scanf("%f",&num);
printf("\n\nThe sin(%f) is\t%f",num,sin(num));
printf("\n\nThe cos(%f) is\t%f",num,cos(num));
printf("\n\nThe log(%f) is\t%f",num,log(num));
getch();
return 0;
}
```

Program 17: Convert Paisa values (input) into rupees

```#include <stdio.h>
#include <conio.h>

main()
{
int paisa;
float rupees;
clrscr();
printf("\nEnter the paisa : ");
scanf("%d",&paisa);
rupees = (float)paisa / 100;

printf("\n%d paisa = %.2f rupees",paisa,rupees);
getch();
}
```

Program 18: Print Sum of series (say. first 8 terms)

```#include <stdio.h>
#include <conio.h>

int main()
{
float sum;
clrscr();

sum = 1 + 1/2.0 + 1/3.0 + 1/4.0 + 1/5.0 +1/6.0 + 1/7.0;
printf("\n1 + 1/2 + 1/3 + 1/4 + 1/5 + 1/6 + 1/7 = %f",sum);
printf("\n\n....Using Integer Calculation");
getch();
return 0;
}

```
