Operators and branching

Let's start with operators so the list starts now...

1. Mathematical:+,-,*,/%
2. Relational:<,<=,>=,==,!=
3. Logical: AND(&&)&OR(||)
4. Unary operator:++(inceremant e.g.i++=i+1),--(e.g.i--=i-1)

then the next topic is branching or condition testing:
if keyword is used for contion testing

e.g.  A C program for if:
if (avg>=75)
{
printf("Congrats you secured first divison");
}

Similarly, else and else if can also be tested

e.g. A C program to find the biggest number between three numbers:

#include <stdio.h>

int main()
{
int a,b,c;

printf("Enter three numbers");
scanf("%d%d%d",&a,&b&c);

if(a>b&&a>c)
{
printf("A is the largest among three numbers"); 
// if a is big than b and c then its the largest
}

else if(b>c&&b>a)
{
printf("B is the largest among three numbers"); 
// if b is big than a and c then its the largest
}
else
{
printf("C is the largest among three numbers"); 
// After checking the over condition it becomes obvious that c is the largest so no need to check it again
}

getch(); //if using turbo c++ to keep the output page displayed

}

remember in else no condition is tested it remains blank
if can exist without else but else cannot and else if can also exist...
