    <p>There is a question in "Problem Solving and Program Design in C" book.I wrote the code, but loop isn't terminating.</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;math.h&gt; void change(double coin_change, int *quarters, int *dimes, int *nickels, int *pennies); int main(void) { int c_dollars, c_quarters = 0, c_dimes = 0, c_nickels = 0, c_pennies = 0; double a_paid, a_due, m_change, coin_change; printf("Enter the amount paid&gt; "); scanf("%lf", &amp;a_paid); printf("Enter the amount due&gt; "); scanf("%lf", &amp;a_due); m_change = a_paid - a_due; c_dollars = floor(m_change); coin_change = m_change - floor(m_change); // shows coin change printf("\n%f\n", coin_change); change(coin_change, &amp;c_quarters, &amp;c_dimes, &amp;c_nickels, &amp;c_pennies); printf("Change is dollars: %d$, quarters: %d, dimes: %d, nickels: %d,\ pennies: %d", c_dollars, c_quarters, c_dimes, c_nickels, c_pennies); return(0); } void change(double coin_change, int *quarters, int *dimes, int *nickels, int *pennies) { int q = 0, d = 0, n = 0, p = 0; do{ if(coin_change &gt;= 0.25){ q++; *quarters = *quarters + q; coin_change = coin_change - q*0.25; } else if( coin_change &gt;= 0.10){ d++; *dimes = *dimes + d; coin_change = coin_change - 0.1; } else if( coin_change &gt;= 0.05){ n++; *nickels = *nickels + n; coin_change = coin_change - (n*0.05); } else if(coin_change &gt;= 0.01){ p++; *pennies = *pennies + p; coin_change = coin_change - (p*0.01); } }while(coin_change&gt;0); } </code></pre> <p>Thank you, I solved problem.The proper code is</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;math.h&gt; void change(double coin_change, int *quarters, int *dimes, int *nickels, int *pennies); int main(void) { int c_dollars, c_quarters = 0, c_dimes = 0, c_nickels = 0, c_pennies = 0; double a_paid, a_due, m_change, coin_change; printf("Enter the amount paid&gt; "); scanf("%lf", &amp;a_paid); printf("Enter the amount due&gt; "); scanf("%lf", &amp;a_due); m_change = a_paid - a_due; c_dollars = floor(m_change); coin_change = (int)((m_change - floor(m_change)) * 100 + 0.5); // shows coin change (int)((m_change - floor(m_change)) * 100 + 0.5) //coin_change = coin_change * 100; printf("\n%f\n", coin_change); change(coin_change, &amp;c_quarters, &amp;c_dimes, &amp;c_nickels, &amp;c_pennies); printf("Change is dollars: %d$, quarters: %d, dimes: %d, nickels: %d,\ pennies: %d", c_dollars, c_quarters, c_dimes, c_nickels, c_pennies); return(0); } void change(double coin_change, int *quarters, int *dimes, int *nickels, int *pennies) { int q = 1, d = 1, n = 1, p = 1; do{ if(coin_change &gt;= 25){ *quarters = *quarters + q; coin_change = coin_change - 25; } else if( coin_change &gt;= 10){ *dimes = *dimes + d; coin_change = coin_change - 10; } else if( coin_change &gt;= 5){ *nickels = *nickels + n; coin_change = coin_change - 5; } else if(coin_change &gt;= 1){ *pennies = *pennies + p; coin_change = coin_change - 1; } }while (coin_change &gt;= 1); } </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.
