C-Programs on Mathematical Problems (Ex 1)

* write a program input, Square of the number.

#include<stdio.h> #include<conio.h> void main( )         {         int num,square;          clrscr( );          num = 7;         square = num * num;         printf("the square of a number is : %d ",square);        getch( );        }

Output:-

the square of a number is : 49

* write a program input, Qube of the number.

#include<stdio.h> #include<conio.h> void main( )       {       int n,qube;        clrscr( );        n = 3;       qube = n * n * n;       printf("the qube of a number is : %d ",qube); getch( ); }

Output:-

the qube of a number is : 27

* Write a Program input,Base and Height of a Triangle, calculate area of Triangle.

#include<stdio.h> #include<conio.h> void main( )         {         int b,h;         float area;          clrscr( );          b = 5;         h = 4;         area =1/2 * b * h;         printf("Area of Triangle is : %f",area);        getch( );        }

Output:-

Area of Triangle is: 10.000000
