i am doing my code in borland 5.02

i am trying to write a program that allows the user enter in two strings when prompted

the program performs certain manipulation with the second string and then adds the result to the first string.

the program should give me the user the choice of searching a string for a particular character,
reversing the string ,changing the case of the string and reversing and changing the case of the string the output of the above string manipulation must be preceded by the first string.

the program should be written using modular programing techniques such as functions using parameters where possible to reduce the use of global variables.

the user should be allowed to repeat any of the string manipulations more than once in the same run of the program and be allowed to change the input strings to be manipulated during a run of the program.

i have written out a code but it is completely wrong and i am trying to get better at c++ any help with this program.
