State the output

#include
int a = 20;
void main()
{
fun1();
printf(" ");
fun1();
printf(" ");
fun1();
printf(" ");
}

fun1()
{
static int b = 10;
b++;
printf("%d", b++);
b=12;
printf(" ");
printf("%d", b++);
}

A 10 12 10 12 10 12
B 11 12 11 12 11 12
C 11 12 14 12 14 12
D Error "static variable re-assignment"

You have a program containing the following statements:

#define ARRAYSIZE 20
char str[ARRAYSIZE]="Test string";
strcat(str, 'z');

When you run the program, it produces a segmentation fault.

Referring to the above scenario, how do you resolve the problem?
Choice a : Use malloc to dynamically allocate memory, rather than using a fixed array.
Choice b : Change 'z' to 'z\0'
Choice c : Change ARRAYSIZE to 21.
Choice d : Change 'z' to "z"
Choice e : Change strcat to strncat and specify a size of 1.

You are looping through a set of results from an SQL database query,

Looking for a specific sequence of entries. Once the sequence of entries is found, you want to stop the loop and continue the program at the statement following the loop

Given the scenario described above, which line of code do you use?

Choice a : if (strcmp (DBSequence, "SEQUENCE")==0) continue;
Choice b : if (strcmp (DBSequence, "SEQUENCE")=0) break;
Choice c : if (strcmp (DBSequence, "SEQUENCE")==0) break;
Choice d : if (strcmp (DBSequence, "SEQUENCE")==0) return 0;
Choice e : if (strcmp (DBSequence, "SEQUENCE")==0) exit;

If the size of the array is less than the number of initializers then,

a. Extra values are being ignored
b. Generates an error message
c. Size of Array is increased
d. Size is neglected when values are given

Which one of the following is printed when this code is executed

int x;
int z=0;
for( x=0; x<5; x++) { z++; if( x <3 ) continue; if( x>3 ) break;
z++;
}
printf(“%d\n”, z);

a Z=1
b. Z=6
c. Z=7
d. Z=9
e. Z=10

1. When the function below is called with a pointer to an open file that contains only three characters A, B and C which one of the following is printed

void listFile( FILE * fp )

{
int c;

while( c = fgetc(fp) != EOF )

{

printf(“%d”, c);

}

printf(“\n”);

}


a. ABC1

b. 1111

c. The characters AB followed by an infinite number of C characters

d. 6566671

e. 0001
