1b. scanf("%d", &num);
    scanf("%s", str);
2. What is printed as the output of the following program fragment?
int xx =07;        // declare and assign 7 to  memory location of xx
printf("%d:, xx);  // look at what is sotred at memory location of xx, and print as decimal 
printf("%.3d\n", xx); // look at what is sotred at memory location of xx, and print as decimal,
                      // but pad to 3 digits (i.e. 003) 

3. Write a program which outputs the following result when the user inputs a float.
   The 3.14 in italic means the user input value.
   Enter a float number: 3.14
   The number 3.14 consists of 3 and 14
   The sum of two pars is 17

  Use scanf function to obtail the needed pieces (3 dot 17). 
  Make the program work without using %f specifier.
