What is the type of the variable b in the following declaration?
#define FLOATPTR float*
FLOATPTR a,b;
a) float b) float pointer c) int d) int pointer
What would be the output of the following program?
main()
{
int y=128;
const int x=y;
printf("%d",x);
}
a) 128 b) Garbage value c) Error d) 0
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, in which order the functions would be called?
a= f1(23,14)*f2(12/4)+f3();
a) f1, f2, f3 b) f3, f2, f1
c) The order may vary from compiler to compiler d) None of the above
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);
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.
What would be the output of the following program?
main()
{
int i=4;
switch(i)
{
default:
printf("n A mouse is an elephant built by the Japanese");
case 1:
printf(" Breeding rabbits is a hair raising experience");
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?
#define SQR(x) (x*x)
main()
{
int a,b=3;
a= SQR(b+2);
printf("%d",a);
}
a) 25 b) 11 c) error d) garbage value
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.
We should not read after a write to a file without an intervening call to fflush(), fseek() or rewind() < TRUE/FALSE>
True
