If I have a menu with some options how do i make the program return to the menu after performing one of the options.

Well the menu is in a loop right? Place continue after the options. Make sure the loop breaks when the user wants to exit the program!
haha i'm dumb. Thanks a bunch
You could place all the options in functions, and call the functions from the menu, always leaving the menu in global context.
Code:#include <stdio.h> void J(char*a){int f,i=0,c='1';for(;a[i]!='0';++i)if(i==81){ puts(a);return;}for(;c<='9';++c){for(f=0;f<9;++f)if(a[i-i%27+i%9 /3*3+f/3*9+f%3]==c||a[i%9+f*9]==c||a[i-i%9+f]==c)goto e;a[i]=c;J(a);a[i] ='0';e:;}}int main(int c,char**v){int t=0;if(c>1){for(;v[1][ t];++t);if(t==81){J(v[1]);return 0;}}puts("sudoku [0-9]{81}");return 1;}
