Arithmetic operators
| Operator | Detils |
|---|
| + | Addition of two operands |
| - | Subtraction of two operands |
| * | Multiplication of two operands |
| / | Division of two operands |
| % | Reminder of a division |
| ++ | Increment by one |
| -- | Decrement by one |
Examples of Arithmetic Operators.
#include <stdio.h>
int main()
{
int x=30 ,y=20;
int result;
result = x + y; // Addition
printf(" Output : %d \n", result);
result = x - y; // Subtraction
printf(" Output : %d \n", result);
result = x * y; // Multiplication
printf(" Output : %d \n", result);
result = x / y; // Division
printf(" Output : %d \n", result);
result = x % y; // reminder of the Division
printf(" Output : %d \n", result);
}
output
Output : 50
Output : 10
Output : 600
Output : 1
Output : 10
Logical operators
| Operator | Detils |
|---|
| && | And operator. Output true only if all operands are true |
| || | Or operator. Output true if any one of the operand is true |
| ! | Not operator. True if out put of condition is false |
Examples ( Output is after comment )
#include <stdio.h>
int main()
{
int x=40 ,y=50;
int result;
result= (x==40) && (y ==30);
printf(" Output : %d \n", result ); // 0
result= (x==40) || (y ==30);
printf(" Output : %d \n", result ); // 1
result= !(x==40) || (y ==30);
printf(" Output : %d \n", result ); // 0
}
Relational operators
Here output is always True or False. It can be 1 or 0
| Operator | Detils |
|---|
| == | Equal To |
| < | Less than |
| > | Greater than |
| <= | Less than or equal to |
| >= | Greater than or equal to |
| != | Not equal to |
Example of Relational Operators ( output are shown with comments )
#include <stdio.h>
int main()
{
int x=30 ,y=20;
printf(" Output : %d \n", x == y); // 0
printf(" Output : %d \n", x < y); // 0
printf(" Output : %d \n", x > y); // 1
printf(" Output : %d \n", x <= y); // 0
printf(" Output : %d \n", x >= y); // 1
printf(" Output : %d \n", x != y); // 1
}
