Replace$1$With$2-$ A function to replace all occurrences of one character in an

array with two characters, as long as the array is large enough

to hold the additional characters. If the array cannot hold the

additional characters, the function should leave the array

unchanged. The function should return true if it changed the

values in the array and false if it did not.

Replace$1$With$2$ takes five arguments: a single$-$subscripted array

of characters, the size of the array, a character to find, and

two characters to replace the found character with.

Consider the character array

char $x[12]=$ "graf fase";

pictured below:

The function call Replace$1$With$2(x,12,\text{'}f\text{'},\text{'}p\text{'},\text{'}h\text{'})$; should

return true, and after the function call the array should hold

the values shown below:

Note: If the character array in the example above was of size

$11$ instead of $12,$ the function call Replace$1$With$2($x$,11,$

$\text{'}f\text{'},\text{'}p\text{'},\text{'}h\text{'})$; would return false and leave the array

unchanged $($since the array is not big enough to hold the

cstring "graph phase"$)$
