Finding factorial of a number using recursive call in MIPS programming - c

Question

This is the C source code
#include <stdio.h>
int main() {
printf("The Factorial of 10 is %d\n", fact(10));
}
int fact(int n) {
if (n < 1)
return (1);
else
return (n * fact(n - 1));
}
I am converting a C Programming function to a MIPS, but when I run the MIPS program I am getting an error for the .ascii section.
.text
.globl main
main:
subu $sp,$sp,32 # Stack frame is 32 bytes long
sw $ra,20($sp) # Save return address
sw $fp,16($sp) # Save old frame pointer
addiu $fp,$sp,28 # Set up frame pointer
li $a0,10 # Put argument (10) in $a0
jal fact # Call factorial function
la $a0,$LC # Put format string in $a0
move $a1,$v0 # Move fact result to $a1
jal printf # Call the print function
lw $ra,20($sp) # Restore return address
lw $fp,16($sp) # Restore frame pointer
addiu $sp,$sp,32 # Pop stack frame
jr $ra # Return to caller
.rdata
$LC:
.ascii “The factorial of 10 is %d\n\000”
.text
fact:
subu $sp,$sp,32 # Stack frame is 32 bytes long
sw $ra,20($sp) # Save return address
sw $fp,16($sp) # Save frame pointer
addiu $fp,$sp,28 # Set up frame pointer
sw $a0,0($fp) # Save argument (n) to use for Recursive Call
lw $v0,0($fp) # Load n
bgtz $v0,$L2 # Branch if n > 0
li $v0,1 # Return 1
jr $L1 # Jump to code to return
$L2:
lw $v1,0($fp) # Load n
subu $v0,$v1,1 # Compute n - 1
move $a0,$v0 # Move value to $a0
jal fact # Call factorial function
lw $v1,0($fp) # Load n
mul $v0,$v0,$v1 # Compute fact(n-1) * n
$L1: # Result is in $v0
lw $ra, 20($sp) # Restore $ra
lw $fp, 16($sp) # Restore $fp
addiu $sp, $sp, 32 # Pop stack
jr $ra # Return to caller
It's giving me an error for the .ascii code section saying it shouldn't be in the .text:
Error in ".ascii" directive cannot appear in text segment
It's also saying that:
"$L1": operand is of incorrect type

I am going out on a limb here because I am not 100% sure what you are running this on, but some sims like MARS don't recognize the rdata segment. You can try using just .data.
Also, if you are on something like WinMIPS64, you may want to try placing the .data segment at the top of the code. I understand what you are doing is right in some environments and but doesn't work in others, so give it a whirl.
May I suggest you try these things separately, just in case.
