Question

How do you convert a string to an integer in RISC-V, RARS? No strtol functions or sprintf (they are not in RARS).

Answer 1

Step-by-step explanation:

In RISC-V, RARS, you can use the atoi function to convert a string to an integer. Here's an example:

# Load the address of the string into a register

la a0, string

# Call the atoi function

call atoi

# The result will be in register a0

Note that the ' atoi ' function expects the address of the string to be in register a0, and it will store the result in the same register. Also, make sure that the string is null-terminated, otherwise the function may not work correctly.
