Answer: C. Data type
Explanation:
data types are defined as the data storage format that a variable can store a data to perform a specific operation. Data types are used to define a variable before its use in a program. Size of variable, constant and array are determined by data types.
Explanation:
The difference between entry condition loop is and exit - condition loop is that the entry condition loops first checks the condition to enter the loop body if the condition true then the loop body is executed otherwise loop body is not executed while the exit-condition loops first executes the loop body and then the condition for the loop is checked.
There are three loops in C that are as following:-
- For
- While
- Do While
Among these three loops While and For loops are entry condition loops and Do While loop is exit condition loop.
For example:-
for(int i=0;i<10;i++)
{
printf("%s","John Doe\n");
}
If the initial value of i should have been 10 then loop body didn't had executed.
int i=0;
while(i<4)
{
printf("%s","John Doe\n");
}
If you try to run this while loop nothing will print on the screen because the condition is false.So the compiler will not enter the loop body and will skip over it.
int i=5;
do{
printf("%s","John Doe\n");
}while(i<4);
Even if the condition is false.You will see that the John doe have been printed one time on the screen because first the body is executed then the condition is checked.
