I dont understand how this program works. We didnt declared anything for getchar, how does it works ? What does the empty loop do ?

We input first and last name separated by a space, the first character of the first name is assigned to initial and then the while loop iterates the getchar through the characters until a space is encountered, that is in case here, our last name.

The second while loop prints the last name character by character and then the last printf is executed

Thank you so much !

There is space to tell scanf to print space before taking next char input, otherwise all your chars will be stacked on other.

Cant we use '\t' for some tab ?

I haven't tried it, last used scanf back in 1400 BC or something

What does %.2f means,I know %f means float specifier,but what does the numerical value and the point means?plz any one clarify this

Liam

%.2f means output as a float number, and reserve 2 digits after decimal point.

i believe \w matches any whitespace

could be wrong

The above is to find average In this I have a doubt,in the first line Mark[10] is used ,why mark has size 10 what if number n<10 or more than 10 is given as input

It points to the no. Of digits like 1234567892 Not 10 or 11

Liam

For this snippet of code: when `n < 0` output is 0; when `n == 0` divided by zero error will be raise: when `0 < n <= 10`, despite risk of overflow, it works correctly; when `n > 10`, segmentation fault caused by index out of range might be raised.

Liam

Practically speaking, only for finding average, recoding these input in an array is useless.

Actually I am now studying arrays,the example is given so I have doubt in it

Liam

It shows how to store data into and load data from an array...… but for the intention of the code, hmmmm……

I think marks[10] mean array of int marks which can store 10 values

Bruce

Is it mean exactly 10?

Bruce

Or less than 10 also possible

Anonymous

Ya less than 10 also

Bruce

Kk,thanks

Anonymous

It mean it we can store less than or equal to 10 bt we cant store more than 10 values

You can ask for n, then allocate the array. If you want do it in advance you need to initialize it w/ an upper bound that you need to control when you ask for n (something like n max is 10)

Oh, for this exercise the array is useless 😅 it makes the algorithm more complex than it should be

Param Veer

Yes

Bruce

Actually I am practicing arrys, it a problem in that excersise

Param Veer

Ok

Param Veer

You should practice more
