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
