C Program for Arithmetic Operations and Expression Evaluation

PROBLEM:

a) Write a C program to perform the arithmetic operations on two integer numbers.

b) Write a program to evaluate the following expressions by reading the necessary values from the keyboard.

i. (ax + b)/(ax – b)

ii. 2.5 log x + Cos 320+ | x2+ y2 |

iii. ax5 + bx3 + c

iv. aekt

Write a C program to perform the arithmetic operations on two integer numbers.

a) Solution

#include
#include
#include
void main()
{	int a,b,c,d,e,f,g;
	clrscr();
	printf("Enter the values of a and b:");
	scanf("%d %d",&a,&b);
	c=a+b;
	d=a-b;
	e=a*b;
	f=a/b;
	g=a%b;
	printf("\nAddition of numbers is: %d",c);
	printf("\nSubtraction of numbers is: %d",d);
	printf("\nMultiplucation of numbers is: %d",e);
	printf("\nDivision of numbers is: %d",f);
	printf("\nRemainder of numbers is: %d",g);
	getch();
}

(ax + b)/(ax – b)

b) (i) Solution

#include
#include
#include
void main()
{
	int a,b,x;
	float y;
	clrscr();
	printf("Enter the values of a,b,x:");
	scanf ("%d %d %d",&a,&b,&x);
	y=((a*x+b)/(a*x-b));
	printf("\nThe result is: %f",y);
	getch();
}

2.5 log x + Cos 320+ | x2+ y2 |

b) (ii) Solution

#include
#include
#include
void main()
{
	int x,y;
	float c;
	clrscr();
	printf("Enter the values of x,y:");
	scanf("%d %d",&x,&y);
	c=(2.5*log(x)+cos(32*3.14/180)+abs(x*x+y*y)+sqrt(2*x*y));
	printf("\nThe result is: %f",c);
	getch();
}

ax5 + bx3 + c

b) (iii) Solution

#include
#include
#include
void main()
{
	int x,y;
	clrscr();
	printf("Enter the values of x:");
	scanf ("%d",&x);
	y=(pow(x,5)+10*(pow(x,4))+8*(pow(x,3))+4*x+2);
	printf("\nThe result is: %d",y);
	getch();
}

{
	int a,k,t;
	float f;
	clrscr();
	printf("Enter the values of a,k,t:");
	scanf ("%d %d %d",&a,&k,&t);
	f=(a*exp(k*t));
	printf("\nThe result is: %f",f);
	getch();
