## area under curve, C/C++ Programming

Assignment Help:

Write a program to find the area under the curve y = f(x) between x = a and x = b, integrate y = f(x) between the limits of a and b.

```#include
float
start_point,            /* GLOBAL VARIABLES */

end_point,
total_area;
int
numtraps;
main( )
{
void
input(void
);
float
find_area(float
a,float
b,int
n); /* prototype */

print(“AREA UNDER A CURVE”);
input( );
total_area = find_area(start_point, end_point, numtraps);
printf(“TOTAL AREA = %f”, total_area);
}
void
input(void
)
{
printf(“\n Enter lower limit:”);
scanf(“%f”, &start_point);
printf(“Enter upper limit:”);
scanf(“%f”, &end_point);
printf(“Enter number of trapezoids:”);
scanf(“%d”, &numtraps);
}
float
find_area(float
a, float
b, int
n)
{
float
base
, lower, h1, h2;    /* LOCAL VARIABLES */

float
function_x(float
x);    /* prototype */

float
trap_area(float
h1,float
h2,float
base
);/*prototype*/

base
= (b-1)/n;
lower = a;
for
(lower =a; lower <= b-base
; lower = lower + base
)
{
h1  =  function_x(lower);
h1  =  function_x(lower + base
);
total_area += trap_area(h1, h2, base
);
}
return
(total_area);
float
trap_area(float
height_1,float
height_2,float
base
)
{
float
area;    /* LOCAL VARIABLE */

area = 0.5 * (height_1 + height_2) * base
;
return
(area);
}
float
function_x(float
x)
{
/* F(X) = X * X + 1 */

return
(x*x + 1);
}

Output

AREA UNDER A CURVE
Enter lower limit: 0
Enter upper limit:  3
Enter number of trapezoids: 30
TOTAL AREA   =  12.005000

AREA UNDER A CURVE
Enter lower limit: 0
Enter upper limit: 3
Enter number of trapezoids: 100
TOTAL AREA = 12.000438```
