Relational Operators
1. check if a length is greater than 2 feet and less than 3 feet
2. taxRate is over 25% and income is less than $20000
3. temperature is less than or equal to 75 or humidity is less than 70%
4. age is over 21 and age is less than 60
5. age is 21 or 22
6. For what value(s) of x would this condition be true?
(x < 1) && (x > 10)
7. For what value(s) of y would this condition be true?
(y >= 1) && (y <= 10)
Write appropriate if statements for each of the following conditions:
8. If the slope is less than .5, set a variable named flag to zero, else set flag to one.
9. Write a program to input an integer number. The program should then output the number and a message saying whether the number is positive, negative, or zero.
10. Write a program to input three numbers and print out the largest number.
11. Write the statements to input a water temperature (in Fahrenheit) and print out the state of the water – freezing, boiling, liquid
Explanation / Answer
1. (length>2) && (length<3)
2. (taxRate>25) && (income<20000)
3. (temperature<=75) && (humidity<70)
4. (age>21) && (age<60)
5. (age==21) || (age==22)
6. for any value of X, condition can not be true
7. y=1,2,3,4,5,6,7,8,9,10
8. if(slope<0.5){
flag=0;
}
else{
flag =1;
}

#include <stdio.h>
int main()
{
int num;
printf("Enter a number: ");
scanf("%d",&num);
if(num > 0 ){
printf("%d is positive ",num);
}
else if(num <0){
printf("%d is negative ",num);
}
else{
printf("%d is zero ",num);
}
return 0;
}
10.
#include <stdio.h>
int main()
{
int num1,num2,num3;
printf("Enter three number: ");
scanf("%d",&num1);
scanf("%d",&num2);
scanf("%d",&num3);
if(num1>num2){
if(num1>num3)
printf("%d ",num1);
else if(num3>num2)
printf("%d ",num3);
}
else{
if(num2>num3)
printf("%d ",num2);
else
printf("%d ",num3);
}
return 0;
}

#include <stdio.h>
int main()
{
float tem;
printf("Enter Fahrenheit temperature: ");
scanf("%f",&tem);
if(tem <=32)
printf("Freezing ");
else if(tem >= 212)
printf("Boiling ");
else
printf("Liquid ");
return 0;
