Not putting // before the start of single statement comment is a compiler error. Not putting the */ after the termination of block comment is a compiler error.

When you are using SWITCH case, it is important to keep in mind that the inclusion of DEFAULT LABEL. This will inform you whether you are executing your program in right or wrong way. So, it is always recommended to use DEFAULT LABEL in the SWITCH st

Semoclone ( ; ) is one of the best sensitive symbols in programming. Placing a semicolon ( ; ) after the WHILE or FOR loop is not a syntax error. So it will not be reported by the compiler. However, it is considered to be a logical error as it change

The test expression done on exact statement. The good habit of using test expression on exact or fulfill statement. So do not use floating point numbers for checking for equality in the test expression.

Specifier is a typedef-name and a very sensitive in C programming. Using an incorrect specifier for the data type being read or written will generate a run time error.

Solving any mathematical problem there are used some equation. So, to solve our problem we used three equations:

For CIRCLE: Π * radius^{2}

For triangle: 0.5 * height * base

For rectangle: height * width

For CIRCLE: Π * radius

For triangle: 0.5 * height * base

For rectangle: height * width

// AHF C PROGRAM SOLVING //solving here basic type of programming problem

#include<stdio.h> #include<math.h> #define pf printf int main() { double radius,a,b,height,width,res1=0.0,res2=0.0,res3=0.0; //area for circle pf("\nEnter value for circle.............."); pf("\nEnter the radius of the circle: "); scanf("%lf",&radius); res1=3.1416*radius*radius; //area for triangle pf("\nEnter value for triangle.............."); pf("\nEnter the first length: "); scanf("%lf",&a); pf("\nEnter the second length: "); scanf("%lf",&b); res2=.5*a*b; //area for rectangle pf("\nEnter value for rectangle.............."); pf("\nEnter the height: "); scanf("%lf",&height); pf("\nEnter the width: "); scanf("%lf",&width); res3=height*width; //total output pf("\nThe area of the circle is : %lf",res1); pf("\nThe area of the triangle is = %lf",res2); pf("\nThe area of the rectangle is = %lf",res3); return 0; }

Enter value for circle..............

Enter the radius of the circle: 2.5

Enter value for triangle..............

Enter the first length: 2

Enter the second length: 3

Enter value for rectangle..............

Enter the height: 8

Enter the width: 6

The area of the circle is : 19.635000

The area of the triangle is = 3.000000

The area of the rectangle is = 48.000000

Enter the radius of the circle: 2.5

Enter value for triangle..............

Enter the first length: 2

Enter the second length: 3

Enter value for rectangle..............

Enter the height: 8

Enter the width: 6

The area of the circle is : 19.635000

The area of the triangle is = 3.000000

The area of the rectangle is = 48.000000
