[C] How to read numbers from file?

Hi!

I've got a file for example:

Hello 123 456
123
Good day very good day
None 56.67

Code (markup):

I want to read 123 , 456, 123 and 56.67 numbers without text.

I found something like that:

#include <stdio.h>

	FILE *fi;
	FILE *fo;

int main()
{
	float a[20];
	int i, n, x, z;
	float limit;
	char line[150];
	char letter[25];
	i=0;



	fi = fopen("lab03_in.txt", "r");


	fo = fopen("output.txt", "w");


	while (fgets(line,1500,fi)!=NULL)
{

	sscanf(line,"%f", &limit);
	//fscanf(fi,"%f", &limit);
	a[i] = limit;
	i++;

}
	printf("How many numbers would you like to input?  ");
	scanf("%d", &x);

	for (n = 0; n < x; n++)
	{
	printf("%.3f\n", a[n]);
	}

	


fclose(fi);
fclose(fo);
getch();
	return 0;
}

Code (markup):

But it doesn't work for numbers between words and only for 1st number if it's also on the beginning of each line.


Thanks,
mp
