There’s a chart in Code Complete that compares the productivity of working in different languages:
Programmers working with high-level languages achieve better productivity and quality than those working with lower-level languages. Languages such as C++, Java, Smalltalk, and Visual Basic have been credited with improving productivity, reliability, and comprehensibility by factors of 5 to 15 over low-level languages such asassembly and C (Brooks 1987, Jones 1998, Boehm 2000). You save time when you don’t need to have an awards ceremony every time a C statement does what it’s supposed to do. Moreover, higher-level languages are more expressive than lower-level languages. Each line of code says more. The [following table] shows typical ratios of source statements in several high-level languages to the equivalent code in C. A higher ratio means that each line of code in the language listed accomplishes more than does each line of code in C.
