Point out error, if any, in the following program
main()
{
int i=1;
switch(i)
{
case 1:
printf("nRadioactive cats have 18 half-lives");
break;
case 1*2+4:
printf("nBottle for rent -inquire within");
break;
}
}
No error. Constant expression like 1*2+4 are acceptable in cases of a switch.
Point out the error, if any, in the following program
main()
{
int a=10,b;
a>= 5 ? b=100 : b=200;
printf("n%d",b);
}
lvalue required in function main(). The second assignment should be written in parenthesis as follows:
a>= 5 ? b=100 : (b=200);

main()
{
int i=4;
switch(i)

break;
case 2:
printf("n Friction is a drag");
break;
case 3:
printf("n If practice make perfect, then nobody's perfect");
}
}
a) A mouse is an elephant built by the Japanese b) Breeding rabbits is a hare raising experience
c) All of the above
What is the output of the following program?

main()
{
int a,b=3;
a= SQR(b+2);
printf("%d",a);
}
a) 25 b) 11 c) error d) garbage value
In which line of the following, an error would be reported?
1. #define CIRCUM(R) (3.14*R*R);
2. main()
3. {
4. float r=1.0,c;
5. c= CIRCUM(r);
6. printf("n%f",c);
7. if(CIRCUM(r))==6.28)
8. printf("nGobbledygook");
9. }
a) line 1 b) line 5 c) line 6 d) line 7
In the following code;
#include
main()
{
FILE *fp;
fp= fopen("trial","r");
}
fp points to:
a) The first character in the file.
b) A structure which contains a "char" pointer which points to the first character in the file.
c) The name of the file. d) None of the above.
If the program (myprog) is run from the command line as myprog 1 2 3 , What would be the output?
main(int argc, char *argv[])
{
int i;
for(i=0;i
If the following program (myprog) is run from the command line as myprog 1 2 3, What would be the output?
main(int argc, char *argv[])
{
int i,j=0;
for(i=0;i
If the following program (myprog) is run from the command line as myprog monday tuesday wednesday thursday,
What would be the output?
main(int argc, char *argv[])
{
while(--argc >0)
printf("%s",*++argv);
}
a) myprog monday tuesday wednesday thursday b) monday tuesday wednesday thursday
c) myprog tuesday thursday d) None of the above
Point out the error in the following program
main()
{
const int x;
x=128;
printf("%d",x);
