Question

C Languagge:

1. What will be printed from the following program segments? (5 points each)
a. for (int x = 1; x <= 20; x++)
{
for (int y=1; y<=5; y++)
printf("%d", x);
printf("\n");
} //for
b. for (int x = 20; x >= 1; x--)
{
printf("%d\n", x);
x--
} //for
c. x = 12;
do
{
printf("%d\n", x);
x--;
}while (x<7);

2. What is the output of the following program segment? (5 points each)
a.
int count =0;
while (count++ < 10)
printf("This loop can repeat statements\n");
b.
int count =5;
while (--count > 0)
printf("\t%d",count);

3. Assume that the following code is correctly inserted into a program: ( 5 points
each)
int s = 0;
for (i = 0; i < 5; i++)
{
s = 2 * s + i;
printf("%d\n", s);
}
a. What is the final value of s?
b. If a semicolon is inserted after the right parenthesis in the for loop
statement,what is
the final value of s?
c. If the 5 is replaced with a zero in the for loop control expression, what is
the final value of s?
