All of the above<\/strong><\/p>\n<p>You can pass copies of individual structure members, copies of entire structures, and pointers to structures to functions.<\/p>\n<ul>\n<li><strong>Passing copies of individual structure members<\/strong><\/li>\n<\/ul>\n<p>When you pass a structure member to a function, the function receives a copy of the member&#8217;s value. This means that any changes you make to the member in the function will not be reflected in the original structure.<\/p>\n<p>For example, consider the following code:<\/p>\n<p>&#8220;`struct my_struct {<br \/>\n  int x;<br \/>\n  int y;<br \/>\n};<\/p>\n<p>void change_x(my_struct *s) {<br \/>\n  s-&gt;x = 10;<br \/>\n}<\/p>\n<p>int main() {<br \/>\n  my_struct s = {1, 2};<br \/>\n  change_x(&amp;s);<br \/>\n  printf(&#8220;%d\\n&#8221;, s.x); \/\/ prints 10<br \/>\n}<br \/>\n&#8220;`<\/p>\n<p>In this example, the function <code>change_x()<\/code> receives a copy of the structure member <code>s.x<\/code>. The function changes the value of <code>s.x<\/code> to 10, but this change does not affect the original structure. When the function returns, the value of <code>s.x<\/code> is still 2.<\/p>\n<ul>\n<li><strong>Passing copies of entire structures<\/strong><\/li>\n<\/ul>\n<p>When you pass an entire structure to a function, the function receives a copy of the entire structure. This means that any changes you make to the structure in the function will be reflected in the original structure.<\/p>\n<p>For example, consider the following code:<\/p>\n<p>&#8220;`struct my_struct {<br \/>\n  int x;<br \/>\n  int y;<br \/>\n};<\/p>\n<p>void change_structure(my_struct s) {<br \/>\n  s.x = 10;<br \/>\n  s.y = 20;<br \/>\n}<\/p>\n<p>int main() {<br \/>\n  my_struct s = {1, 2};<br \/>\n  change_structure(s);<br \/>\n  printf(&#8220;%d %d\\n&#8221;, s.x, s.y); \/\/ prints 10 20<br \/>\n}<br \/>\n&#8220;`<\/p>\n<p>In this example, the function <code>change_structure()<\/code> receives a copy of the entire structure <code>s<\/code>. The function changes the values of <code>s.x<\/code> and <code>s.y<\/code> to 10 and 20, respectively. These changes are reflected in the original structure, so when the function returns, the value of <code>s.x<\/code> is 10 and the value of <code>s.y<\/code> is 20.<\/p>\n<ul>\n<li><strong>Passing pointers to structures<\/strong><\/li>\n<\/ul>\n<p>When you pass a pointer to a structure to a function, the function receives a pointer to the original structure. This means that any changes you make to the structure through the pointer will be reflected in the original structure.<\/p>\n<p>For example, consider the following code:<\/p>\n<p>&#8220;`struct my_struct {<br \/>\n  int x;<br \/>\n  int y;<br \/>\n};<\/p>\n<p>void change_structure_pointer(my_struct *s) {<br \/>\n  s-&gt;x = 10;<br \/>\n  s-&gt;y = 20;<br \/>\n}<\/p>\n<p>int main() {<br \/>\n  my_struct s = {1, 2};<br \/>\n  change_structure_pointer(&amp;s);<br \/>\n  printf(&#8220;%d %d\\n&#8221;, s.x, s.y); \/\/ prints 10 20<br \/>\n}<br \/>\n&#8220;`<\/p>\n<p>In this example, the function <code>change_structure_pointer()<\/code> receives a pointer to the structure <code>s<\/code>. The function changes the values of <code>s.x<\/code> and <code>s.y<\/code> to 10 and 20, respectively. These changes are reflected in the original structure, so when the function returns, the value of <code>s.x<\/code> is 10 and the value of <code>s.y<\/code> is 20.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;copies of individual structure members&#8221;
