Question

p unugil pairs of tiput Values until the user enters nonnumeric input. Modify exercise 7 so that it uses a function to return the value of the calculation. Write a program that requests lower and upper integer limits, calculates the sum of all the integer S: uares from the square of the lower limit to the square of the upper limit, and displays the answer. The program should then continue to prompt for limits and display answers until enters an upper limit that is equal to or less than the lower limit. A sample run should look something like this sq the user Enter lower and upper integer limits: 5 9 The sums of the squares from 25 to 81 is 255 Enter next set of limits: 3 25 The sums of the squares from 9 to 625 is 5520 Enter next set of limits: 5 5 20

please send me within 15 mins if possible

Answer 1

#include <stdio.h>
int main(void)
{
int index, lower, upper, square, total, input;
printf("Enter lower and upper integer limits: ");
for (input = scanf("%d %d", &lower, &upper); input == 2; printf("Enter the next set of limits: \n"), scanf("%d %d", &lower, &upper))
{
for (index = lower; index <= upper; index++)
{
square = index * index;
total += square;
}
printf("The sums of the squares from %d to %d is %d\n", lower * lower, upper * upper, total);
}
return 0;
}
int main(void)
{
int index, lower, upper, square, total;
printf("Enter lower and upper integer limits: ");
while (scanf("%d %d", &lower, &upper) == 2)
{
total = 0;
for (index = lower; upper > index; index++)
{
square = index * index;
total += square;
}
printf("The sums of the squares from %d to %d is %d\n", lower * lower, upper * upper, total);
printf("Enter the next set of limits: \n");
}
return 0;
}
UPDATE*****
Thanks to everyone's help I think I finally got it:
include
int main(void)
{
int index, lower, upper, square, total;
printf("Enter lower and upper integer limits: ");
while (scanf("%d %d", &lower, &upper) == 2)
{
while (lower < upper)
{
total = 0;
for (index = lower; index <= upper; index++)
{
square = index * index;
total += square;
}
printf("The sums of the squares from %d to %d is %d\n", lower * lower, upper * upper, total);
printf("Enter the next set of limits: \n");
scanf("%d %d", &lower, &upper);
}
printf("Done");
}
return 0;

}

int index, lower, upper, square, total, input;
while(1)
{
total = 0;
printf("Enter lower and upper integer limits: ");
fflush(stdout);
input = scanf("%d %d", &lower, &upper);
if(input != 2) continue;
if(upper <= lower) break;
for (index = lower; index <= upper; index++)
{
square = index * index;
total += square;
}
printf("The sums of the squares from %d to %d is %d\n", lower , upper, total );
}
printf("Done\n");
