} | | 1 | | How can u say that a given point is in a triangle?
1. with the co-ordinates of the 3 vertices specified.
2. with only the co-ordinates of the top vertex given. | | 1 | | int i;
main(){
int t;
for ( t=4;scanf("%d",&i)-t;printf("%d\n",i))

struct a
{
int x;
struct a *b;
} | | 1 | | write the function. if all the character in string B appear in
string A, return true, otherwise return false. | Google | 10 | | void main()

} | | 1 | | Is there any difference between the two declarations,
1. int foo(int *arr[]) and
2. int foo(int *arr[2]) | | 1 | | Write out a function that prints out all the permutations of
a string.
For example, abc would give you abc, acb, bac, bca, cab,
cba. You can assume that all the characters will be unique. | Microsoft | 4 | | main()
{
int i=10;
void pascal f(int,int,int);

a. Runtime error.
b. “Hello world”
c. Compile error
d. “hello world” | HCL | 1 | | main()
