| | i want to print a 'double' variable upto 8 decimal places without trailing zeroes. for eg: if a= **10.1234** then print **10.1234** if a= **10.00** then print **10** if a= **10.11111111111** then print **10.11111111** (max of 8 decimal places). how to do it? i searched for it and found this: … |
| | I understood that when you pass the name of the array as an argument to a function we are actually passing the base address of the array, which inturn gets collected by a pointer variable and thus s[i]=*(s+i)=*(i+s)=i[s]. The problem begins when we turn to 2-D arrays. When we want … |
