Hello.

It is very easily to convert one form to another.

CForm[Expand[(x+Sqrt[y])^2]]
Power(x,2) + 2*x*Sqrt(y) + y

InputForm[%]
x^2 + 2*x*Sqrt[y] + y

StandardForm[%]
\!\(x\^2 + 2\ x\ \@y + y\)

CForm[Expand[(x+Sqrt[y])^2]]
Power(x,2) + 2*x*Sqrt(y) + y

FortranForm[%]
x**2 + 2*x*Sqrt(y) + y

StandardForm[%]
\!\(x\^2 + 2\ x\ \@y + y\)

TeXForm[Sqrt[x^2+y^2]]
\sqrt{x^2+y^2}

MathMLForm[%]
<math>
 <msqrt>
  <mrow>
   <msup>
    <mi>x</mi>
    <mn>2</mn>
   </msup>
   <mo>+</mo>
   <msup>
    <mi>y</mi>
    <mn>2</mn>
   </msup>
  </mrow>
 </msqrt>
</math>

OutputForm[%]
      2    2
Sqrt[x  + y ]

As another example consider

str=FromCharacterCode[Table[Random[Integer,{90,120}],{20},{2}]]
{x],rm,]q,_i,v`,to,jm,pq,mh,jx,Zi,a],]n,gm,r^,ci,`w,qf,kg,e[}

CForm[str]
List("x]","rm","]q","_i","v`","to","jm","pq","mh","jx","Zi","a]","]n","gm","r^","ci","`w","qf","kg","e[")

InputForm[%]
{"x]", "rm", "]q", "_i", "v`", "to", "jm", "pq", "mh", "jx", "Zi",
"a]", "]n", "gm", "r^", "ci", "`w", "qf", "kg", "e["}
