Error with cc sunstudio compiler

I compiled that program under turbo C without any problems but with
sunstudi I found those errors:

"pnt02ma1.c", line 37: warning: implicit function declaration: system
"pnt02ma1.c", line 58: operands must have arithmetic type: op "*"

/*-----------------------pnt02ma1.c---------------------
Given those formulas
---inch = cm   /  2.45
---inch =(meter * 100)/2.45


---feet = 12 inch
---yard = 3 feet
---yard = 36 inch
---inch = 1/12 feet
---inch = 1/36 yard

---yard > feet > inch

convert given meter value to (yards , feet , and inches)

1-convert meter to the smallest unit = (inches).
2-obtain yards (biggest required value).
3-obtain the remainder inches after getting yards. m=m%36
4-obtain feet (second biggest required value).
5-obtain the remainder inches after getting feets.i=m%12
