The function replace() either:
</p>
<p>
* replaces characters of the current string with up to num characters from str,
</p>
<pre class="c code c++" style="font-family:monospace;"> beginning at index<span class="sy0">,</span>
with up to num2 characters from str beginning at index2<span class="sy0">,</span>
beginning at index in str<span class="sy0">,</span>
with num2 characters from str beginning at index2<span class="sy0">,</span>
with num2 copies of ch<span class="sy0">,</span></pre>
<p>
* replaces characters in the current string from start to end with num
</p>
<pre class="c code c++" style="font-family:monospace;"> characters from str<span class="sy0">,</span>
copies of ch.</pre>
<p>
For example, the following code displays the string “They say he carved it
himself…find your soul-mate, Homer.”
</p>
<pre class="c code c++" style="font-family:monospace;"> <span class="kw4">string</span> s <span class="sy0">=</span> <span class="st0">"They say he carved it himself...from a BIGGER spoon"</span>;
