c - given a list of numbers, find the first and last times a certain number is entered -

i need create programme that, when user inputs list of integers, finds position of first , lastly entry of number, , number of times specific number shows up.

the proper output supposed this:

enter number find: 4 come in list of numbers (negative quit): 1 8 4 9 3 4 4 8 2 4 10 3 4 2 4 -1 list contains 15 numbers. first occurrence of '4': 3 lastly occurrence of '4': 15 quite few found!

i have working great except 1 thing: since i'm using scanf take in user input each time, instead of putting numbers on 1 line, this:

1 8 4 9 3 4 4 8 2 4 10 3 4 2 4 -1

it this:

1 8 4 9 3 4 4

etc.

is there way have not start new line each entry?

yeah, if utilize \n in printf format string, new line. if don't have character in there, won't. take out , write new line after loop.

likewise, when entering numbers @ prompt, don't press enter after each one. looks supposed come in them separated spaces.

given want display prompt text on same line input, may need flush output too:

printf( "enter list of numbers (negative quit): " ); fflush( stdout ); // input loop. int num; { if( 1 != scanf( "%d", &num ) ) { fprintf( stderr, "bad input\n" ); exit(1); } // input... } while( num != -1 );

c scanf
