    Reading files processing

    I tried to reading this file and write in struct musteri until 'E'.But this doesnt work correctly can you help me?



    Code:
    #include<stdio.h>#include<stdlib.h>
    #include<string.h>
    
    
    struct musteri{
    	float id[10];
    	float x1[10];
    	float x2[10];
    	float x3[10];
    	float x4[10];
    	float x5[10];
    	
    }musteri;
    
    
    int main() {
    	char harf;
    	int i=0;
    	int ch;
    	FILE *d;
    	d=fopen("d.txt","r");
    	
    while ((harf=fgetc(d)) != 'E'){
    
    
    	fscanf(d," %f %f %f %f %f %f  ",&musteri.id[i],&musteri.x1[i],&musteri.x2[i],&musteri.x3[i],&musteri.x4[i],&musteri.x5[i]);
    	
    	i++;
    	
    	
    }
    ch=i;
    i=0;
    
    
    for(i=0;i<ch;i++){
    	
    	printf("%f %f %f %f %f %f",musteri.id[i],musteri.x1[i],musteri.x2[i],musteri.x3[i],musteri.x4[i],musteri.x5[i]);
    	printf("\n\n\n");
    	
    }	
    return 0;
    }

    Well this eats the first character of the 1st line, just ruining your attempt to scanf the rest of the line.

    Normally I would suggest
    Code:
    char buff[BUFSIZ];
    while ( fgets(buff,BUFSIZ,d) ) {
      if ( buff[0] != 'E' ) {
        sscanf(buff," %f %f %f %f %f %f  ",&musteri.id[i],&musteri.x1[i],&musteri.x2[i],
                 &musteri.x3[i],&musteri.x4[i],&musteri.x5[i]);
      } else {
        break; // all done
      }
    }
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
