EXPRESSIONS IN C

EXPRESSIONS IN C

• ARITHMETIC EXPRESSIONS :

• An arithmetic expressions is a combinations of variables , constants , and operators arranged as per the syntax of the language. C can handle any complex mathematical expressions. Some of the examples of C expressions are shown in figure .

• EVALUATION OF EXPRESSIONS :
• Expressions are evaluated using an assignment statement of the form :

              variable = expressions ;

                X = A * B - C ;

                Y = B / C * A;

---

#include <stdio.h>

int main()

{

float x, y, a, b;

a = 10;

b = 20;

x = (a * b) - (10 / b) ; // expression 1

y = b + (a * 30) / a ; // epression 2

printf(" x = %f /n",x);

printf(" y = %f ",y);

return 0;

}

output :  x = 199.500000
              y = 50.000000

Expressions nothing but mathematical calculations, variables , operators and constants.(+, - , / , * , %) .
