Question 1
a. What digits are used in the binary number system?
b.What digits are used in the decimal number system?
c.What digits are used in the octal number system?
d.What digits are used in the hexadecimal number system? \
Question 2
In the following program, there is a call to the print_in_reverse function which
has the following prototype:
void print_in_reverse(float *a, int count);
Using pointers, write this function to print the array in reverse order.
#include <stdio.h>
#define A_SIZE(A) sizeof(A)/sizeof(A[0])
void print_in_reverse(float a[], int count);
int main(void)
{
float values[6] = { 12.1F, 22.2F, 32.3F,
42.4F, 52.5F, 62.6F };
printf("The array in reverse\n");
print_in_reverse(values, A_SIZE(values));
return 0;
}
Question 3
The program below reads two integers. Then a function with the following
prototype is called:
void div_rem(int a, int b, int *divides, int *remains);
This function is passed the two integers. It divides them (using integer division),
and writes the answer over wherever “divides” points. Then it finds the
remainder and writes it into where “remains” points. Thus for 20 and 3, 20
divided by 3 is 6, remainder 2. Implement the div_rem function.
#include <stdio.h>
void div_rem(int a, int b, int *divides, int *remains);
int main(void)
{
int a, b;
int div = 0;
int rem = 0;
printf("enter two integers ");
scanf("%i %i", &a, &b);
div_rem(a, b, &div, &rem);
printf("%i divided by %i = %i "
"remainder %i\n", a, b, div, rem);
return 0;
}
