{
printf("Hi\nthere\nWhat is the output\n?");
}
[/code:1cr6dwhp]
Ans:
OUTPUT:
Hi
there
What is the output
?
----------------------------------------------------------------------------------------------
[i:1cr6dwhp]Exercise 2:
Write a program that declares two floating numbers. Initialize them with float values. Then print their sum and multiplication in two separate lines.[/i:1cr6dwhp]
[code:1cr6dwhp]
#include<stdio.h>
void main(){
/*Declaring two decimal variables (floats)*/
float x,y;
/*Intialising the variables*/
x=233.55;
y=566.22;
/*Printing the sum of the variables*/
printf("The sum of %f and %f is %f\n",x,y,x+y);
printf("The product of %f and %f is %f",x,y,x*y);
}
[/code:1cr6dwhp]
----------------------------------------------------------------------------------------------
[i:1cr6dwhp]Exersise 3 :
Write the output result of multiple function example in this lesson.[/i:1cr6dwhp]
[code:1cr6dwhp]
#include<stdio.h>
main()
{
printf("I am going inside test function now\n");
test();
printf("\nNow I am back from test function\n");
}
test()
{
int a,b;
a=1;
b=a+100;
printf("a is %d and b is %d",a,b);
}
[/code:1cr6dwhp]
Ans:
OUTPUT
I am going inside test function now
a is 1 and b is 101
Now I am back from test function
----------------------------------------------------------------------------------------------
[i:1cr6dwhp]Exercise 4: Why these variable names are not valid ? [/i:1cr6dwhp]
test$var - $ symbol is not allowed in variable declaration, You can use letters, digits and underscore (_) character to make your variable names.
my counter - " "(blank space) is also taken as a character which is also not allowed in variable declaration
9count - First character in a variable name must be a letter or an underscore (_) character.
float - A variable name cannot be a C programming language-reserved word (i.e. Commands and pre defined function names etc)
