There is no difference semantically in both the constructs. For is easy to use. While can be used for the same purpose and vice versa with for loop is true. It depends on choice and of course some specific cases where you can avoid cryptic code. All loops of for can be replaced with while and vice versa,...

for loops basically is used when developer knows number of iterations to be performed is known already : Example : printing table of 10 up to 10 i.e 10 * 10=100 we know number of iteration=10 so for loop can be used for(i=1;i<=10;i++){ printf("%d \n",i); ...

for loops basically is used when developer knows number of iterations to be performed is known already : Example : printing table of 10 up to 10 i.e 10 * 10=100 we know number of iteration=10 so for loop can be used for(i=1;i<=10;i++){ printf("%d \n",i); // already knew iteration=10 so for loop } WHILE loop on other hand is used if developer s not sure or uncertain about number of iterations prior. Example C program to reverse the number : here number n can be anything inputted by user so developer is not sure about number of iteration so while loop while(n != 0) { remainder = n%10; reversedNumber = reversedNumber*10 + remainder; n /= 10; } we can solve this by using for loop also but it is recommended if number of itertion not know use WHILE else if known then FOR. read less

What is the actual size of INT in the C language, 2 or 4 bytes?
The actual size to int is determined by the compiler as the program runs. But theoretically the size is 2 bytes. You can increase the size by adding keyword long infront of it to make the size 4 bytes. Eg int a; // 2 bytes Long int b; // 4 bytes
