Code:
#include <stdlib.h>
int main()
{
char cTestPrag[128]={0x0};
sprintf(cTestPrag, "kill -9 `ps -ef | grep textedit | grep -v %cgrep%c| awk '{print $2}'` ",
'"','"');
system(cTestPrag);
return 0;
}

More easily, just escape the quotes in the string.
const char cTestPrag[]=" kill -9 `ps -ef | grep textedit | grep -v \"grep\"| awk '{print $2}'| xargs` ";

You cannot imbed " in a quoted string. You can escape them \" (which linters - code checkers - usually complain about), or you can use sprintf to place them in the string as single characters.
man sprintf

what is the need for quoting grep as "grep" ?
is that going to make any difference ? It won't.
