5.  What is this program doing ?            pid = fork ( ) ;    int pipefd [2 ];     pipe ( pipefd ) ;     if ( pid == 0 ) {              fclose ( pipefd [1] ;               read ( pipefd [0],  buf, 10 );               fclose ( pipefd [0 ] ) ;     }     else       {               fclose ( pipefd [0] ;               write ( pipefd [1],  "Hi There", 8 );               fclose ( pipefd [1 ] )       }

Given C code: #include <stdio.h>typedef struct compound {  float realNumber;  float imaginaryNumber;} compound; compound add(compound n1, compound n2); int main() {  compound n1, n2, temp;   printf("For the first compound number \n");  printf("Enter the real and imaginary parts: ");  scanf("%f %f", &n1.realNumber, &n1.imaginaryNumber);   printf("\nFor the second compound number \n");  printf("Enter the real and imaginary parts: ");  scanf("%f %f", &n2.realNumber, &n2.imaginaryNumber);   temp = add(n1, n2);  printf("Sum = %.1f + %.1fi", temp.realNumber, temp.imaginaryNumber);   return 0;} compound add(compound n1, compound n2) {  compound temp;   temp.realNumber = n1.realNumber + n2.realNumber;  temp.imaginaryNumber = n1.imaginaryNumber + n2.imaginaryNumber;   return (temp);} Task: Please change the C program above to execute complicated numeral multiplication. Hint: (e+fi)(g+hi) = (eg−fh) + (eh+fg)i

#include <stdio.h> struct Single {     int num; };   void printSingle(int f) {     int binaryNum[33];     int i = 0;     while(f>0)     {         binaryNum[i] = f % 2;         f = f/2;         i++;     }     for (int j=i-1; j>= 0; j--)     {         printf("%d",binaryNum[j]);     } }   int main() {     struct Single single;     single.num = 33;     printf("Number: %d\n",single.num);     printSingle(single.num);     return 0; }

In the C programming language, if all function prototypes are listed at the top of your code, outside and above all functions, you do not need to worry about the order of the function definitions within the code. True False
