This is strange, my output to printf is exacty how i want it.
But the output to a file is not what I expected. My instructor for class is horrible. (long story)
the output to the regular printf is:
Temp Avg High Low
1173 46.00 100 -1
fprintf is :
(null)Temp/ Ave/ High/ Low
(null)1173/ 0.00/ -1 / 0 (the slashes aren't there, I added those to section off the categories and numbers)
I don't get why my file output is dorked up, can anyone point me in the write direction?
Thanks for any help. Yes I am new to programming.
my code isCode:#include<math.h> #include<stdio.h> #include<string.h> #define inp_file "C:\\Users\\John\\Desktop\\ehhh\\temps.txt" #define out_file "C:\\Users\\John\\Desktop\\ehhh\\averages.txt" #define debug 1 int main(void) { FILE *inp, *out; double avg_temp; int High, Low, temp; inp = fopen(inp_file,"r"); out = fopen(out_file,"w"); if (debug) { if (inp == NULL || out == NULL) { printf("File does not exist\n"); return(0); } } while (fscanf(inp,"%d\n", &temp) != EOF) { printf("%d\n", temp); } High = 100; //highest temp Low = -1; //lowest temp avg_temp = 1173 / 25; printf("Temp\t\tAve\t\tHigh\t\tLow\n"); printf("1173\t\t%.2f\t\t%d\t\t%d\n", avg_temp, High, Low); fprintf(out,"%sTemp\t\tAve\t\tHigh\t\tLow\n"); fprintf(out,"%s1173\t\t%.2f\t\t%d\t\t%d", avg_temp, High, Low); fclose(inp); fclose(out); return(0); }
