Removing "\n" character while writing into a file in Shell Script

Here i am taking the text input from the yad ui field and then i am writing that text into a solc.c but that text contains some \n characters , which are directly being written into solc.c

#!/bin/bashlanguage=$(yad --form --field="Select Language:CB" "C!C++" --button="OK:0" --button="Cancel:1" --width=300 --height=100)if [ $? -eq 0 ]; then  selected_language=$(echo "$language" | awk -F"|" '{print $1}')  code=$(yad --form --field="Your Code:TXT" --title="Problem-A Solution" --button="OK:0" --button="Cancel:1" --width=800 --height=600)  if [ $? -eq 0 ]; then    if [ "$selected_language" = "C" ]; then"${code%?}" > "solc.c"        gcc solc.c    elif [ "$selected_language" = "C++" ]; then"${code%?}" > "sol1.cpp"        g++ sol1.cpp    else      echo "Invalid language selected."      exit 1    fi

current solc.c

#include <stdio.h>\n\nint main() {\n    long long a, b;\n    scanf("%lld %lld", &a, &b);\n    printf("%lld\\n", a + b);\n    return 0;\n}\n    return 0;\n }\n

expected :

#include <stdio.h>int main() {    long long a, b;    scanf("%lld%lld", &a, &b);    printf("%lld\n", a + b);    return 0;}

it worked sometime but for the same code it is not working now,and same it follows with sol1.cpp

Also mention ,if there is any other hacks to get rid of the \n being written into the file .
