Description html markup shown to student | <p> Define a function <tt>strcpy()</tt> that takes a 'src' character array and 'dest' character array as input. <tt>src</tt> and <tt>dest</tt> are null-terminated character arrays <strong>(aka C-strings).</strong></p> <strong>Note 1: the destination array should be the first argument, the source the second argument</strong> <p> <strong>Note 2:</strong> The formal argument of a function taking an array usually requires <strong><tt>[]</tt> after the name (e.g. <tt>char src[]</tt>)</strong> but C/C++ supports a second way to accept an array in the formal argument using the <strong><tt>*</tt> (e.g. <tt>char *</tt>)</strong> </p> |

using namespace std; // Copy the characters from the src array to the destination array. // The arguments are passed as dest followed by src and both are // character arrays (C-Strings). void strcpy( \[ REDACTED ]\ dest, \[ REDACTED ]\ src ) { \[ REDACTED ]\ } int main() { char src1[12] = "hello world"; char src2[10] = "bye"; char src3[1] = ""; char dest[21] = "abcdefghijklmnopqrst"; strcpy(dest, src1); cout << dest << endl; strcpy(dest, src2); cout << dest << endl; strcpy(dest, src3); cout << dest << endl; return 0; } |
