CSCE A201 Midterm #1 v2
Name:
This exam is worth a total of 100 points. The exam is open book and open notes. You
can use a calculator or a computer but should be your own work. Show your work or
single zip file.
a) What could go wrong with the code:
if (strvar == “hello”)
printf(“Hi there!n”);
b) Add parenthesis to the expression below to match the order that will be used in C
when evaluating the expression.
3 + 5 % 2 * 10
c) A variable of type char is used to store a character. Why does C allow you to
assign a number to a char variable, for example, char c = 65; ?
d) Fill in the blanks for the program below. The program should calculate the
product of the even integers from 1 to 15 (i.e. 2*4*6*8*10*12*14) and print it.
#include “stdio.h”
int main()
{
int product = ________;
for (int i=1; i 0)
{
value = value + count;
count = count – 2;
}
printf(“Value: %dn”, value);
3) 20 points. Bugs! Find and fix the bugs in the following code snippets.
a) The following code should output “big” if the input is exactly 100 and “small”
otherwise:
int value;
scanf(“%d”,&value);
if (value = 100)
printf(“bign”);
else
printf(“smalln”);
b) The following code should keep asking the user to enter a key until the key pressed
is ‘Y’ or ‘N’, at which point the loop should exit.
char c;
do
{
printf(“Try again? Press Y or N.n”);
scanf(” %c”,&c);
} while ((c!=’Y’) || (c!=’N’));
c) The following should input 5 numbers into the array.
int a[5];
int temp;
for (int i = 1; i
