A researcher obtained a sample of adults and interviewed them about their financial concerns. this is an example of a) <u>cross-sectional survey </u>design.

Cross-sectional surveys assess the prevalence of disease and the prevalence of risk factors at the same point in time and provide a "snapshot" of diseases and risk factors simultaneously in a defined population.

In medical research, social science, and biology, a cross-sectional study is a type of observational study that analyzes data from a population, or a representative subset, at a specific point in time—that is, cross-sectional data.

Another example of a cross-sectional study would be a medical study examining the prevalence of cancer amongst a defined population. The researcher can evaluate people of different ages, ethnicities, geographical locations, and social backgrounds.

True/false: if you attempt to store data past an array's boundaries, it is guaranteed that the compiler will issue an error.
Elenna [48]

If you attempt to store data past an array's boundaries, it is guaranteed that the compiler will issue an error, this is false.

If you attempt to store data past an array's boundaries, it is guaranteed that the compiler will issue an error, If an integer array is partially initialized, the uninitialized elements are going to be set to zero. A vector object automatically expands in size to supply lodging the things stored in it.

Array bound checking refers to determining whether all array references in an exceedingly program are within their declared ranges.

This checking is critical for software verification and validation because subscripting array's beyond their declared sizes may produce unexpected results, security holes, or failures.

If we use an array index that's out of bounds, then the compiler will probably compile and even run.
