Is there a way to have printf() properly print out an array (of floats, say)?

Question

I believe I have carefully read the entire printf() documentation but could not find any way to have it print out, say, the elements of a 10-element array of float(s).

E.g., if I have

float[] foo = {1., 2., 3., ..., 10.}; 

Then I'd like to have a single statement such as

printf("what_do_I_put_here\n", foo); 

Which would print out something along the lines of:

1. 2. 3. .... 10. 

Is there a way to do that in vanilla C?

Answer 1

you need to iterate through the array's elements

float foo[] = {1, 2, 3, 10}; int i; for (i=0;i < (sizeof (foo) /sizeof (foo[0]));i++) {     printf("%lf\n",foo[i]); } 

or create a function that returns stacked sn printf and then prints it with

printf("%s\n",function_that_makes_pretty_output(foo)) 

Answer 2

You have to loop through the array and printf() each element:

for(int i=0;i<10;++i) {   printf("%.2f ", foo[i]); }  printf("\n");
