add python style indenting

now this is valid code:

#include <stdio.h>

int main():
    float a,b int c float cache=1
    printf("Input some numbers: ")
    if (scanf("%f %f %d",&a,&b,&c)!=3):
        printf("Invalid input.\n")
        return 1
    printf("\n")
    if(b==0):
        printf("b is zero\n")
    else:
        printf("%f/%f = %f\n",a,b,a/b)
    if(c>=0):
        for (int i=0 i>c i++):
            cache*=a
        printf("%f^%d = %f\n",a,c,cache)
    else:
        printf("c is negative\n")
    return 0

yeah this is so cursed.
this is the output of the code:
