Initially i = 10.
Since no case is labeled 10, the control goes to default and the value of i is updated to 15, the next time when i entered the loop, its value gets incremented by 1 and it now becomes 16, since no case is labeled 16, the control again goes to default and its value become 21, again when i enters the loop, its value gets incremented by 1 and it now becomes 22, again no case is labeled 22, the control goes to default and the now is updated to 27, this process will continue until the value of i exceeds 50.

You will think the compiler will throw an error because of the header written in (" ") or use of ==. But that's not the case, the header can be imported like this also, and == is a comparison operator. The output of this program will be 1 because == operator(comparison operator) has a higher order of precedence than = operator, and hence it will get executed first. == operator returns the output in 1 or 0, and since the value of charmeleon and charizard are same it will return 1 which will update the value of charmander

According to the order of precedence of operators, bracket operator has a higher precedence than the assignment operator, hence it is executed first, it is evaluated from left to right but it is always the result of the last expression which gets assigned

In C, prefix and postfix operators need integer-value to perform an operation and return r-value. The expression (++prep)++ when executed increments the value of variable i(i is a integer-value) and returns r-value. The compiler generates the error(integer-value required) when it tries to post-increment the value of a r-value.

7. The output will be:

#include <stdio.h>

int main()
{
    char chr = 'a';    
    printf("character = %d.", chr);
    return 0;
}

character = a.

this is also known as an implicit conversion, which is done by the compiler on its own, whenever we use a different format specifier with a different datatype, in this case %d is used for printing a char type value which will finally print the ASCII value of chr
