C Programming language

fscanf Function Reads data from the stream and stores them according to the parameter format into the locations pointed by the additional arguments. The additional arguments should point to already allocated objects of the type specified by their corresponding format tag within the format string.

fscanf (FILE *fptr , const char *format [,address,.....]);

The fscanf function works exactly like the scanf function except that it reads the information from the stream specified by stream instead of standard input device.
