The * vs ++ in *p++ is a question of which to do first. Do we do all of the operations of ++ first or the dereference first? The postfix operator (++) binds tighter so we do all of the ++ operations first, then we do the dereference (*). This is order of operations vs operat...
with the actual code that does the task, the function is defined. Once defined, a function can be called from any portion of the program where it is visible. Functions are a fundamental notion in C programming that is frequently used in the development of larger, more complicated programs. ...
I'm fine! 10 10.23 Hello Value of a = 10 Value of b = 10.23 Value of c = Hello See the output of the above program, print() function is ending with a newline and the result of the next print() function is printing in the newline (next line)....
In which loop control structures can 'continue' be used? Can 'break' or 'continue' be used outside a loop? How does 'break' affect nested loops? Can 'break' be used to exit a switch statement? Is it mandatory to include 'break' after every 'case' in a 'switch' statement? Can '...
My compiler does no padding. // Now let's make some! struct int_and_char iac; union int_or_char ioc; // We already know how structs work: iac.i = 42; iac.c = 'c'; printf("iac.i = %d; iac.c = '%c'\n", iac.i, iac.c); // Prints: iac.i = 42; iac.c = 'c'...
Heap overflow: It occurs when the memory allocated dynamically by the program exceeds the heap size. A heap is a first in first out (FIFO) data structure used to store data that is required for a long time during program running. When the heap overflows, even if the program does not st...

Does the HAR support cyclic dependency? Is dependency transfer supported? For example, can a HAP call the APIs provided by HAR B if it depends on HAR A, which in turn depends on HAR B? How do I fix the "Resource id invalid" error reported when calling resourceManager.getStringResource...
printf("The value of ptr is %u",ptr); return 0; } Note: In C, the null macro may have the type void* but this is not allowed in C++. Null in C# In C#, null means "no object." Information about null and its usages in C# include: You cannot use 0 instead of null in your ...
