Question

Here is my practice code:

int integer_part;

char* string_part = (char*)malloc(sizeof(1000));

char* input_string = (char*)malloc(sizeof(1000)+sizeof(int));

cin>>input_string;

sscanf(input_string, "%s %d", string_part, &integer_part);

printf("scan: %s %d", string_part, integer_part);

I am using this code to take input like abc 2012 but the result will be abc 0

Sadly I didn’t see where the problem is. Can anyone help me with this a little? thank you

Answer 1

This reads only first space delimited string:

cin>>input_string;

Use this way:

cin>> string_part >> integer_part;

Don’t mix C++ and C way of reading from streams.

You can use this way to read string without space delimited:

cin.read ( input_string, sizeof(1000)+sizeof(int) - 1);
size_t read_Len = cin.gcount();
input_string[read_Len] = '\0';

I can understand you need the power of scanf to read data in a given format.
