F.A.Q. of Statistical Algorithms Importer (SAI), here are common mistakes we have found in Linux-compiled Project.
How to use the input parameters
- For example we consider BasicStatistic algorithm:
- DataMiner show the BasicStatistic algorithm in this way:
- C code in sample:
//============================================================================ // Name : BasicStatistic.cpp // Author : Giancarlo Panichi // Version : // Copyright : Your copyright notice // Description : BasicStatistic in C++, Ansi-style //============================================================================ #include <iostream> #include <stdio.h> #include <stdlib.h> #include <string.h> using namespace std; int main(int argc, char **argv) { printf("BasicStatistic"); printf("Operator: %s\n",argv[1]); printf("Maximum number of items considered: %s\n",argv[2]); printf("Input file: %s\n",argv[3]); FILE * finput; char * line = NULL; size_t len = 0; ssize_t read; finput = fopen(argv[3], "r"); if (finput == NULL){ printf("No input file found: %s\n", argv[3]); return -1; } int limit=atoi(argv[2]); int i=0; int value=0; int result=0; while (((read = getline(&line, &len, finput)) != -1) && (i<limit||limit==-1)) { printf("Retrieved line of length %zu and value: %s", read,line); value=atoi(line); if(i==0){ result=value; } else { if (strcmp(argv[1], "max") == 0) { if(value>result){ result=value; } } else { if (strcmp(argv[1], "min") == 0) { if(value<result){ result=value; } } else { if (strcmp(argv[1], "average") == 0) { result=(result+value)/2; } else { break; } } } } i++; } fclose(finput); if (line){ free(line); } //Write result FILE *foutput = fopen("output.txt", "w"); if (foutput == NULL) { printf("Error opening file!\n"); return -1; } fprintf(foutput, "BasicStatistic Result: \n"); fprintf(foutput, "%d\n", result); fclose(foutput); return 0; }
