I want to use zlib library to read a gz file binary data, but gzread () and gzgets () can not read clearly, and automatically quit program

Code:

 
# include & lt; Zlib. H> 
# include & lt; Iostream> 
# include & lt; String> 
using namespace std; 

Int main () 
{
Char * filename="TS21z_X_R2_000100. Gz"; 

GzFile GZFP=gzopen (filename, "rb"); 

If (GZFP==NULL) 
{
Printf (" error "\ n"); 
return false; 
} 

//distribution of 4 bytes (float) 
Char data [4]. 
Memset (data, 0, sizeof (data)); 

//read 4 bytes 
Gzread (GZFP, data, 4); 
//gzgets (GZFP, data, 4); 
Printf (" \ n % f ", * (float *) data); 
Gzclose (GZFP); 
Printf (" successfully read earthquake data \ n "); 

return 0; 
}

If it is a binary is not the same, you need to specify the parameters such as the "rb" if there are other parameters, the building Lord your check
