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

Answer is a)128. Here we are not modifying const value. We are just assigning value to const variable.

main()
{
int i;
clrscr();
printf("%d", &i)+1;
scanf("%d", i)-1;
}
">Main() { int i; clrscr(); printf("%d", &i)+1; scanf("%d", i)-1; }
A) Runtime error. Access violationB) Compile error. Illegal syntaxC) None of the aboveD) Runtime errorExplanation: printf( ) prints address/garbage of i, scanf() dont have & sign, so scans address for i +1, -1 dont have any effect on code.

The printf will give some junk value (address) and scanf will wait for the input from user. once u enter a value u'll get Bus error(coredump).

Array elements are stored in contiguous memory and arrays can hold elements of one type only. Therefore, nArrElmt = sizeof(arr)/sizeof(arr[0]);

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
shivprasad
- Nov 2nd, 2012
B) float pointer
jbode
- Oct 29th, 2012
B is a plain float.
FLOATPTR a,b; expands to float* a,b;, which is *parsed* as float (*a),b;. The * is bound to the declarator, not the type specifier, so only a is declared as a pointer to float. -
char *b = "World";
clrscr();
printf("%s", strcat(a,b));
}
">Main(){ char *a = "Hello "; char *b = "World";clrscr(); printf("%s", strcat(a,b));}
A) HelloWorldB) Hello WorldC) HelloD) None of the above

I think segmentation fault error is dependent on the operating system you are using. I think if you run the code in Windows it will not give any error while when you run the same code in UNIX you will gate segmentation fault.
