Thread: Ordering names

I need to order the names in a file (alphabetically), I managed to put the names in an array and find the first name. However, Im having trouble in printing the rest of the names. Heres part of the code:

/*matriz1 and matriz2 are [150][45], alumnos is FILE *alumnos */

Code:

  memset(matriz1,'\0',sizeof(matriz1));
  memset(matriz2,'\0',sizeof(matriz2));
  while(fgets(buffer,255,alumnos)) {
                int len;
                len = strlen(buffer);
                if(buffer[len-1] == '\n') {
                        buffer[--len] = 0;
                        if(buffer[len-1] == '\r')
                                buffer[--len] = 0;
                }

                if(!buffer[0] || buffer[0] == '#')
                        continue;
		
				strncpy(matriz1[i], buffer, 45);
				matriz1[i][44]='\0';
//				printf("\nI: %i, valor: %s", i, matriz1[i]);
				fflush(stdout);
				i++;
	}
	


	m=i;
/*
	limit=str_search(matriz1[0],"#",1);
	memset(row,'\0',sizeof(row));
	strncpy(row, matriz1[0], limit);
	row[limit-1]='\0';
*/		
 for(j=0; j<=m; j++) {
	if(strlen(matriz1[j])<=1)
		continue;
		
	limit=str_search(matriz1[j],"#",1);
	memset(row,'\0',sizeof(row));
	strncpy(row, matriz1[j], limit);
	row[limit-1]='\0';
	
	for(i=0; i<=m; i++){
		if(strlen(matriz1[i])<=1)
			continue;
		/* Matriz1[i] es menor que row */
		if(strncmp(row,matriz1[i],limit-1)>0){
			limit=str_search(matriz1[i],"#",1);
			memset(row,'\0',sizeof(row));
			strncpy(row, matriz1[i], limit);				
		}
	}
	
	printf("\n\nEl menor es : %s",row);
	strncpy(matriz2[index_matriz2], row, 45);
	matriz2[index_matriz2][44]='\0';
	matriz1[i][0]='\0';
	
	index_matriz2++;	

	memset(matriz1[i],'\0', sizeof(matriz1[i]));

	for(aux=0; aux<150; aux++){
		if(strlen(matriz1[aux])>1)
			limit=str_search(matriz1[aux],"#",1);
			memset(row,'\0',sizeof(row));
			strncpy(row, matriz1[0], limit);
			row[limit-1]='\0';
			break;
	}
 }	

	printf("\n\nImprimiendo matriz 2\n");
	for(i=0; i<=m; i++){
		printf("\nI: %i; %s",i, matriz2[i]);
		fflush(stdout);	
	}

Thanks
