MIPS Assembly: INT to STRING function only 2 chars (cut off last char) 0. Firstly, the MIPS pseudocode to convert an integer to string is as follows - void int2str(num, str): // str: pointer to string version of integer 'num' if num < 0: *str = ASCII of '-' // negative number str++ num *= -1 push -1 to MIPS stack // end of stack marker while num > 0: push num % 10 to MIPS stack num = num // 10 You will want to read the System V Application Binary Interface, MIPS RISC Processor Supplement. So for example the string containing "Chuck" would be 0x436875636b00 in ASCII. In older posts (even in the first one about Mips) we used arrays of character without know it, now, we are able to understand that every characters of a string has a specific address of memory: for example if we have the string "Hello" and we want to know the address of the "o", we just take the address of the array (which is equal to the A C-style string (or some assembly), is a series of consecutive bytes terminated with a nul-character. Modified 4 years, 5 months ago. The problem is pretty simple: a function like substr doesn't really exist in isolation -- it's part of a string library, and to make it useful, you just about need to at least sketch out how the library as a whole fits together, how you represent your data, etc. Find and fix vulnerabilities MIPS User input integers into array then printing them out. If start is greater than end, arguments are swapped: (4, 1) = (1, 4).
