NettetThe basic idea is to transfer the value of one variable to another and take the value of the second variable and put it to first. Example: a = 6 b = 3 swap (a,b) //using a swap … Nettet18. sep. 2013 · a=2; b=a++ + a++; As we know in an assignment expression assocciativity is right--> left. so here right side a value 2 is taken as the operand and after that a's …

What does the compiler do here: int a = b * (c * d * + e)?

Nettetint a=1; // initialization int b=0; // initialization b=++a + ++a; // find the pre-increment i.e. 2 increments of 'a' so now 'a' in this step will be incremented by 2 so now 'a' will contain 1+2=3. so now a=3. Again before assignment compute 'a+a' which is '3+3'=6 printf("%d %d",a,b); //3 6} Just a trick:- always compute the pre-increments in ... Nettet3. des. 2024 · int (int a, int b); wouldn't work since the compiler would go find that function which doesn't exist and has no name.
