String with two words: 1)String, 2) $double

[Roger]

I have a string saved in memory with exactly one space in the middle and two substrings; the string is formatted like this:

"Mike $120.00"

The first word will be saved as a string, the second needs to be converted to a float. Please, how can I do separate this string at the space and convert the 2nd string into a float?

Thanks in advance.

Assuming that the first word does not contain whitespace, you could use sscanf() with a format string like "%Ns $%f", where N is the maximum length of the destination string (i.e., excluding the null terminator).

char name[50];
float amount;
...

sscanf(buffer, "%s $%f", name, amount);

warning: format â%fâ expects type âfloat *â, but argument 4 has type âdoubleâ

I don't know why I'm getting this warning. The variable 'amount' is declared as a float, so I do not see why the compiler is making this warning.

You should be taking the address of amount, so it should be:

sscanf(buffer, "%49s $%f", name, &amount);

You might also want to check that sscanf returned 2.

Thank you very much for your help laserlight.
