Question

I need help with how to do if else if statements in C
I am doing this in Xcode 4.6.3, while learning how to program in C
The code that I have done so far and the directions that I am following using to follow this part of the assignment are going to be in the next post that I am dong
I will give a medal to anyone who helps me, and if I think that there answer helps me

Answer 1

Code:

#include <stdio.h>



int main(){

int age = 37;

if(age < 18-29)

{

age = 0-18;

} else {

age = 19-29;

}

if(age < 30-49)

{

age = 30-39;

} else {

age = 40-49;

}

if(age < 50-90)

{

age = 50-59;

} else {

age = 60-90;

}

return 0;

}

Answer 2

That is the above code which I have been working on so far

Answer 3

Here are the directions that I am using to do this part of the assignment:

2. Create a int variable called age and set the value to 37.

Using an if...else...if statement series printf() the

following message based on the value of age:

0-18 You’re just a youngster!

19-29 Have fun now, while you can!

30-39 Time to focus on family and career

40-49 These are the best years of your life!

50-59 Better be saving for retirement.

60+ Enjoy retirement. I hope you saved enough

money

3. Compile and test your code and insure you get the expected

result. Change the value of the age variable and retest

your program.

Answer 5

In the debugger console, no code is outputted. It says that it ran without any issues.

Answer 6

You need to have a printf statement to see any output. Also when you write
if (age < 18-29)
it is interpreted by the compiler as
if (age < -11)
so you just want
if (age < 19)

Answer 7

Another very useful tip is that you don't need multiple if-statements in this case, you can chain them like this:
if (age < 19) {
printf("You’re just a youngster!");
} else if (age < 30) {
...
} else if (age < 40) {
...
} etc...

Answer 8

In this the program will compare the age variable with 19, if it's less, it will print the thing and jump out of the "if-chain". Otherwise it will compare age with 30, etc.
