Hello,

I am unable to do printf with floating numbers read from a text file  while integer value is working.

My original work is to read floating values  into an array. The  code i have written is below

Your code looks ok

I tried changing the heap size and stack size to 0x400.

If you did indeed set the stack and heap size to 0x400, that should be enough:

There is no output at all in the console?

Thanks

Hello Ki,

The console is showing values upto 4. But the loop is given upto 10.

Sometimes it is showing upto 6 values. never it showed 10 values.

My real situation is to take upto 1200 values.

Hello Ki,

Yes when I did Step Over I got the values till ten.If debug is not done the console is not printing full.

My real problem is to check weather all values are assigned into an array if it is a float value. When I am printing the float value this is my console.

The code is shown below.

ecgArray[i]=j;
printf(" j val= %f\n", ecgArray[i] );

Ok i am using a scaled version of the input to avoid floating point error.

I get all ten, regardless of if I step or just run. The code example you sent me, is that the whole code that you are testing with? Or just a snippet/example? Can you provide your executable?

Thanks

Hello Ki,

#include <stdio.h>
int main(void)
{

float c,ecgArray[1200]; // To store a character read from file

int i,ff;
FILE *fp;
fp = fopen("E:\\processor\\ecgData.txt", "r");
char buff[255];
float j;

for(i=0;i<10;i++)
{
fgets(buff, 255, (FILE*)fp);
printf("%d:",i+1);
printf("%d: %s\n",i+1,buff);
sscanf (buff," %f", &j);

ff = j*1000;

ecgArray[i]=j;

printf(" j val= %f\n", ecgArray[i] );

}

fclose(fp);

return 0;
}

Hi Ki,

I am attaching the text file used in the program.The main file is the same code i have send above.No changes are made.
