Q.Write a C program to accept the height of a person and determine whether he is a dwarf, average man, taller or if he possess an abnormal height. The textbook presents this worked program, transcribed exactly as printed (including its printed errors):

#include<stdio.h>  
void main()  
{  
float ht;  
printf("Enter the height (in centimeters)\n");  
scanf("%f, &ht);  
if (ht<130.0)  
    printf("Dwarf\n");  
else if ((ht>=130.0)&&(ht<=155.0))  
    printf("Average height\n");  
else if ((ht>=150.0)&&(ht<=185.0))  
    printf("Taller\n");  
else  
    printf("Abnormal height\n");  
}  
/*End of main()*/  

Sample output printed in the textbook:

Enter the height  
154.0  
Average height  

By default a C program runs its statements one after another, but decision (conditional) control statements let it choose between alternative paths depending on a condition. They are the basis of all decision-making programs.

• if statement - executes a block only when its condition is true; if the condition is false the block is skipped.

  if (condition)
      statement;
  

• if-else statement - provides two alternatives: one block runs when the condition is true, the other when it is false.

  if (condition)
      statement1;
  else
      statement2;
  

• Nested-if / else-if ladder - an if (or if-else) placed inside another, used to test several conditions in turn. This is how a program picks the largest of three numbers, or grades a value into ranges such as short, average and tall. …
