## Code for Program for frequency counting in C Programming

```#define   MAXVAL    50
#define   COUNTER   11
main()
{
floatvalue[MAXVAL];
int          i, low, high;
int   group[COUNTER] = {0,0,0,0,0,0,0,0,0,0,0};
/* . . . . . . . .READING AND COUNTING . . . .  . .*/for( i = 0 ; i < MAXVAL ; i++ )
{
/*. . . . . . . .READING OF VALUES . . . . . . . . */
scanf("%f", &value[i]) ;
/*. . . . . .COUNTING FREQUENCY OF GROUPS. . . . . */
++ group[ (int) ( value[i] + 0.5 ) / 10] ;
}
/* . . . .PRINTING OF FREQUENCY TABLE . . . . . . .*/
printf("\n");
printf(" GROUP     RANGE     FREQUENCY\n\n") ;
for( i = 0 ; i < COUNTER ; i++ )
{
low  = i * 10 ;
if(i == 10)
high = 100 ;
else
high = low + 9 ;
printf("  %2d    %3d to %3d       %d\n",
i+1, low, high, group[i] ) ;
}
}
