Every if statement can written using a switch...case statement.

The following program does not compile. Identify the reason(s) why.

int main()
{

int know = 3;
switch (know)
{
  case 3:       printf("one\n");
                break;
  case 1+1+1:   printf("hi\n");
                break;
  default:      printf("bye\n");
}

return 0;

}

Multiple files - each opened as a distinct file stream - can be used for reading/writing data within a C program.

Consider the following:

typedef struct node {
    int data;
    struct node *next;
} NODE;

NODE *xyz[20];

What would happen if the following piece of code was compiled?

#include <stdio.h>

int main()
{
        int a,b,c;
        scanf("%d",&a);
        scanf("%d",&b);
        float c = a+b;
        printf("%f\n",c);
        return 0;
}
