    <p>I'm writing a program in C that finds the time of flight and height at impact of a projectile and my program is compiling, but it's coming out with the wrong values for the solutions. Any idea what I might be doing wrong?</p> <pre><code>/* *Finds final time and height of a projectile when it reaches the target */ #include &lt;stdio.h&gt; /* printf, scanf definitions */ #include &lt;math.h&gt; /* cos definition */ #define G 32.17 /* gravitational constant */ int main(void) { double theta; /* input - angle(radians)of elevation */ double distance; /* input - distance(ft)to target */ double velocity; /* input - projectile velocity(ft/sec) */ double time; /* output - time(sec)of flight */ double height; /* output - height at impact */ /* Opening explanation to user */ printf("This program computes the duration of a projectile's flight and its height above the ground when it reaches the target. To use this program, enter the angle, the distance, and the velocity after each of the prompts.\n\n"); /* Get angle, distance, velocity. */ printf("Enter the angle of elevation in radians:"); scanf("%f", &amp;theta ); printf("Enter the distance to target in feet:"); scanf("%f", &amp;distance ); printf("Enter the projectile velocity in ft/sec:"); scanf("%f", &amp;velocity ); /* Get time of flight */ time = distance / (velocity * cos(theta)); /*Get height at impact */ height = velocity * sin(theta) * time - ( (G * time*time) / 2.0 ); /* Display time of flight */ printf("The time of flight is %fs seconds.\n", time); /* Display height at impact */ printf("The height at impact is %fm feet.\n", height); system("pause"); return (0); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
