Question

Why is my buffer too small?

I am compiling a word-definition class and I am having some problems. I am producing an output but I cannot insert another word definition pair without having an error that states: "Buffer is too small". With the output I am producing, I am able to insert a pair(a word and its definition) until the error occurs. When I have searched up the variables I used to add the word and its definition through C++(I did this by running my program and making a breakpoint, then I went to the debug option and went down to windows, then I went to memory and memory1) and search up newWord(the variable I used to add the new word), the memory address appeared on the right hand side. This also occurs for the definition(newDef). But when I try to find the list of words and definitions in my output, C++ says there is no words or definitions. I am confused. How do I fix this problem?

Answer 1

Such an error might be the result of using the wrong size of variable. The variable size is exceeding the limit or the variable has been introduced by length and type manually. It is always better to refer to the variable directly.

Another reason could be the use of invalid packages or modules in the program.

A mismatch in data type can also cause the problem of too small a buffer. For example, if a string is expected and one is a passing number, it will cause an error.
