Which is the first successful high level programming language?
D
Correct answer
Explanation
FORTRAN (FORmula TRANslation), developed by IBM and John Backus's team and released in 1957, was the first widely successful high-level programming language. It enabled scientists and engineers to write code using mathematical notation rather than assembly or machine code. C (1970s) and C++ (1980s) came decades later, while QBASIC was a 1990s educational language.
