Cの算術演算子

次の表は、C言語でサポートされているすべての算術演算子を示しています。変数 A が10を保持し、変数 B が20を保持すると仮定します-

Operator	Description	Example
PLUS	Adds two operands.	A PLUS B = 30
−	Subtracts second operand from the first.	A − B = -10
*	Multiplies both operands.	A* B = 200
/	Divides numerator by de-numerator.	B/A = 2
%	Modulus Operator and remainder of after an integer division.	B % A = 0
++	Increment operator increases the integer value by one.	A++ = 11
—	Decrement operator decreases the integer value by one.	A-- = 9

例

Cで利用可能なすべての算術演算子を理解するために、次の例を試してください-

#include <stdio.h>

main() {

   int a = 21;
   int b = 10;
   int c ;

   c = a + b;
   printf("Line 1 - Value of c is %d\n", c );

   c = a - b;
   printf("Line 2 - Value of c is %d\n", c );

   c = a * b;
   printf("Line 3 - Value of c is %d\n", c );

   c = a/b;
   printf("Line 4 - Value of c is %d\n", c );

   c = a % b;
   printf("Line 5 - Value of c is %d\n", c );

   c = a++;
   printf("Line 6 - Value of c is %d\n", c );

   c = a--;
   printf("Line 7 - Value of c is %d\n", c );
}

上記のプログラムをコンパイルして実行すると、次の結果が生成されます-

Line 1 - Value of c is 31
Line 2 - Value of c is 11
Line 3 - Value of c is 210
Line 4 - Value of c is 2
Line 5 - Value of c is 1
Line 6 - Value of c is 21
Line 7 - Value of c is 22
