Hi guys we got a homework assignment. We have to convert if statements that have "!=" in them to branch zero(==0) or branch positive(>0).
However the code generates weird input when I do that.
Could someone tell me what I am doing wrong?
original code:
Code:#include <stdio.h> int ch, spaces = 0; int diff; int main(void) { while( (ch = getchar()) != EOF) { if( ch == ' ') { if( ++spaces == 3) { putchar('*'); spaces = 0; } } if(ch!=' ') { for( int i=0; i<spaces; i++) putchar(' '); spaces = 0; putchar(ch); } } return 0; }
edited code:
Code:#include <stdio.h> int ch, spaces = 0; int diff; //to calculate difference for if-statements int main(void) { while( (ch = getchar()) != EOF) { if( ch == ' ') { if( ++spaces == 3) { putchar('*'); spaces = 0; } } diff = ch-' '; if(diff==0) { for( int i=0; i<spaces; i++) putchar(' '); spaces = 0; putchar(ch); } } return 0; }
