1 IF STATEMENT General form of an if without an : If (a Boolean expression) A sequence of statement General form of an if with an : If (a Boolean expression) A sequence of statements a sequence of statements EX(1) Write a program to find the value of z under the following conditions x 2 +7x+1 x<0 7x+17 0<x 10 Z= x 2 +10x x 25 25x+100 other values #include<math.h> int z; int x; printf( "Give an integer value \n"); scanf("%d",&x); if(x<0) 1

2 z = pow(x,2)+7*x+1; if(x>0 && x<=10) z=7*x+17; if(11<=x && x<= 25) z=pow(x,2)-10*x+15; z=25*x+100; printf(" \nthe value of z= %d",z); getch( ); 2

3 Write a program to print integers in the closed interval[0,77] which accept division over 3 with out remainder. int a; for(a=0;a<=77;a++) if(a%3==0) printf(" %d",a); 3

4 Write C program to show if an integer is divisible by another integer with out remainder short int n,m; printf("give 2 Integer Numbers\n"); scanf("%d%d",&n,&m); if(n%m==0) printf("%d is divisible by %d",n,m); printf("%d is not divisible by %d",n,m); 4

5 //program to compute commission value int sales; float commission; printf(" enter sales value in $ "); scanf("%d",&sales); if(sales<1000) printf(" no commission\n"); if (sales>1000 && sales <=2000) commission=sales*0.05; 5

6 if(sales >2000 && sales<=5000) commission= sales*0.08; commission= sales*0.10; printf("\n commission in $%f",commission); write a program to find the absolute value of any number 6

7 Int x; printf("give the value of x \n"); scanf("%d",&x); if(x<0) printf("the absolute value of x= %d",-x); printf("the absolute value of x= %d",x); give the value of x The absolute value of x= 9876 Write a program that asks the user to enter 2 integers, then prints the larger number followed by the words is larger if the numbers are equal,print the message these numbers are equal. int a; int b; printf("give the first number \n"); scanf("%d",&a); printf("give the second number \n"); scanf("%d",&b); if(a>b) printf("%d is the large number",a); 7

8 if(b>a) printf("%d is the large number",b); printf("the two numbers are equals"); Write a program to reads 2 integers and determines and prints if the first is a multiple of the second 8

9 int a; int b; int y; int z; printf("give the first number \n"); scanf("%d",&a); printf("give the second number \n"); scanf("%d",&b); y=int(a/b); z=y*b; if(z==a) printf("the first number is multiple of the second number"); printf("the first number is not multiple of the second number"); 9

10 use square root function to Write c program to show if an triangle is right angle /* program to show if triangle is right #include<math.h> short int A,B,C; printf("give the length of sides A,B,c \n"); scanf("%d%d%d",&a,&b,&c); if(a==sqrt(c*c+b*b)) printf("the triangle is right angle"); if (B==sqrt(A*A+C*C)) */ 11

11 printf("the triangle is right angle"); if(c==sqrt(a*a+b*b)) printf("the triangle is right angle"); printf("the triangle is not right angle"); Use pow function and logical operator OR to write c program to show if an triangle is right angle or not right angle 11

12 #include<math.h> short int A,B,C; printf("give the length of A,B,C\n"); scanf("%d%d%d",&a,&b,&c); if(a==sqrt(pow(c,2)+pow(b,2)) B==sqrt(pow(A,2) +pow(c,2)) C==sqrt(pow(A,2)+pow(B,2))) printf("the triangle is right angle"); printf("the triangle is not right angle"); 12

13 Use power function and square root function to show if an triangle is right angle. #include<math.h> main)( short int A,B,C; printf("give the length of sides A B C \n"); scanf("%d%d%d",&a,&b,&c); if(a==sqrt(pow(c,2)+pow(b,2))) printf("the triangle is right angle"); if(b==sqrt(pow(a,2)+pow(c,2))) printf("the triangle is right angle"); 13

14 if(c==sqrt(pow(a,2)+pow(b,2))) printf("the triangle is right angle"); printf("the triangle is not right angle"); getch)); Write a program to compute the cost of electricity power in your hose if you know that the prices of each unit is as follows Less than or equal dinar Greater than 500 and less than dinar 14

15 Greater than 1000 and less than or equal dinar Greater than dinar short int q; long int cost; printf(" Give the value of quantity\n"); scanf("%d",&q); if(q<0) printf("error negative value\n"); if(q>0&&q<=500) cost=q*10; if(q>500&&q<=1000) cost= 5000+(q-500)*20; if(q>1000&&q<=1500) cost= (q-1000)*30; cost= (q-1500)*50; printf("the cost of electricity power=%d",cost); 15

16 Write c program to find the integers in the closed interval[0,100] which accept division over 5 without remainder short int i; for(i=0;i<=100;i++) if(i%5==0) printf("%d",i); 16

17 Write C program to find the integers between 0 and 20 which does not accept division over 5 without remainder. short int i; for(i=0;i<=20;i++) if((i%5)!=0) printf(" %d",i); 17

18 Write C program to find the integers between 0and 20 which doesn't accept division over 2,3,5 without remainder short int i; for(i=0;i<=20;i++) if((i%5)!=0&&(i%3)!=0&&(i%2)!=0) printf(" %d",i); 18

19 Write C program to print even and odd numbers in the closed interval[0,20] /*program even numbers */ int i; for(i=0;i<=20;i++) if(i%2==0) printf(" The number %d is even number\n",i); printf("\n\n\n"); for(i=0;i<=20;i++) 19

20 if((i%2)!=0) printf(" The number %d is odd number\n",i); 21
