Determine whether the following identifiers can be used to define variables in a C program.

Given the following definitions:

int a[] = {15,13,2,7,9,1,8,3,6,4}, *p = &a[2], *q = a+7;

determine the value resulting from the evaluation of each of the following expressions.

Given the following definitions:

int a[] = {/* some initializers*/}, *p = a+3;

for each of the following expressions, choose an equivalent expression from the listed choices.

Consider the following code fragment:

int vector[5] = {1, 2, 3, 4, 5}, *pv = vector, value = 3;
for (size_t i=0; i < sizeof(vector)/sizeof(int); ++i) { 
  *pv++ *= value; 
}

If the code fragment doesn't compile, write [for compile-time error]. If the code fragment has undefined behavior at runtime, write [for undefined behavior]. Otherwise, write the the sum of the values in array vector after the code fragment's execution.

Write the exact characters printed to standard output by the following code fragment:

char s[] = "HSjodi", *p = s;
for (; *p; ++p) {
  --*p;
}
printf("%s", s);

Write the exact text printed to standard output stream by the following code fragment:

char name[] = {'D','i','g','i','\0','p','e','n'};
fputs(name, stdout);
