voidfoo(void){int32_t a; a = bar();int32_t b; /* Wrong, there is already executable statement */} 你可以在下一个缩进级别中声明新的变量 int32_t a, b;a = foo();if (a) {int32_t c, d; /* OK, c and d are in if-statement scope */ c = foo();int32_t ...
Here, if statement is terminated by semicolon (;). Thus,Error: 'else' without a previous 'if' in Cis occurred. To fix the error remove the semicolon (;) after the if statement. Correct Code #include<stdio.h>intmain(){inta=10;if(a==10){printf("True\n");}else{printf("False\n...
