include
float func(int x){ int i; float sum=1.0 for(i=2;i<=x;i++) sum=sum+1.0/i; return i;}Main(){ int m; float c; printf(\n Please enter 1 integer number:); scanf("%d",&m); c=fun(m); printf("\n the sum = %f",c); return 0;}

帮我找出错误啊!谢谢啊!!!!!!!有重谢啊

Include
Main(){char ac=gets();if((c>'a' && c<'z') | (c>'A' && c<'Z'));printf (%f %f %f \n , c-1 , c , c+1);}

都有错误!帮个忙啊!
