Other notation in the sample program may seem odd. C allows for special assignment operators, such as += or /= (as used in the sample program). The statement Sign in to download full-size image is equivalent to Sign in to download full-size image Similarly, Sign in to download full-si...
Operators on the same line have equal precedence. When operators of equal precedence appear in the same expression, a rule must govern which is evaluated first. All binary operators except for the assignment operators are evaluated from left to right; assignment operators are evaluated right to ...
This program will read two integer numbers and calculate the arithmetic operators, in this example we used switch case and if else statement. User will enter a choice after entering two numbers and based on user choice program will return the result....
