臂组件-输出错误

Question

我的目标是采用ary标签中的数字并将其分类为相应的代。我当前遇到的问题是我得到的输出完全关闭。会不会是我的循环不正常？

我期望的输出是

Greatest Generation: 1
Generation X: 1
Not Applicable: 1

我现在得到的是

Lost Generation: 66328
Generation Y: 1995673600

下面是我所拥有的

            .data
    str1:   .asciz  "Lost Generation: %d\n"
    str2:   .asciz  "Greatest Generation: %d\n"
    str3:   .asciz  "Baby Boomer Generation: %d\n"
    str4:   .asciz  "Generation X: %d\n"
    str5:   .asciz  "Generation Y: %d\n"
    str6:   .asciz  "Generation Z: %d\n"
