int f(int);
int main(void){ int i, t, funval; // Make sure to change low and high when testing your program int low=-3, high=11; for (t=low; t<=high;t++){ printf("f(%2d)=%3d ",t,f(t)); }
// Your code here... return 0; }

int f(int t){ // example 1 return (t*t-4*t+5);    // example 2 // return (-t*t+4*t-1);    // example 3 // return (sin(t)*10);    // example 4 // if (t>0) // return t*2; // else // return t*8; }
. (15 points) Complete the attached program plot.c to plot a function f (t),e.g. f (t)-t2-4t+5 for values of t between two values as specified as two variables low and high on line 11 in plot.c. Note. first nested loops are NOT allowed in your program secondIam the definition of f (tl when testi ng your program:third.am g low and high when testing your program, Please find a few example f (t) shown as comments in the bottom ofplot.c. The following are their corresponding outputs

Explanation / Answer

#include<stdio.h>

int low, high;
int f_min, f_max;

int f(int t) {
   return t*t + 4*t + 5;
}

void calc_min_max() {
   int i;
   f_min = f_max = f(low);
   printf("f(%d) = %d ",low, f_min);
   int y;
   for (i = low+1; i <= high; i++) {
       y = f(i);
       printf("f(%d) = %d ",i, y);
       if (y > f_max)
           f_max = y;
       else if (y < f_min)
           f_min = y;
   }
}

char *get_new_line() {
   char *line = malloc(sizeof(char) * (f_max - f_min + 2));
   int i;
   for(i = 0; i < f_max - f_min + 1; i++)
       line[i] = ' ';
   line [f_max - f_min + 1] = '';
   return line;
}

void print_plot() {
   int i;
   char *line;
   printf("       ");
   for (i = f_min; i <= f_max; i=i+5)
       printf("%-5d",i);
   printf(" ");
   for (i = low; i<=high; i++) {
       line = get_new_line();
       line[f(i) - f_min] = '*';
       printf("t = %3d%s ",i,line);
       free(line);
   }
}

int main() {
   printf("Enter lower limit: ");
   scanf("%d",&low);
   printf("Enter upper limit: ");
   scanf("%d",&high);
   calc_min_max();
   print_plot();
}
